Das gibt Schlieren, Kalkränder und im Insektenfilm einen Schmierfilm, der die Sicht bei Gegenlicht verschlechtert. Fülle stattdessen ein Konzentrat aus der CW1:100-Linie nach, auch im Sommer. Das Tensid löst Insekten an, statt sie nur zu verteilen.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eEine Linie für ein Problem freie Sicht\u003c\/h3\u003e\n\n\u003cp\u003eDr. Wack CW1:100 löst genau eine Aufgabe sauber: die Scheibe vor dir frei halten. Alles in der Serie zahlt auf Sicht ein, von der Waschanlage bis zum eingetrockneten Insektenrest außen.\u003c\/p\u003e\n\n\u003cp\u003eDer Markenname CW1:100 verweist auf das Konzentrat-Prinzip. Das Produkt geht stark verdünnt ins Wischwasser, ein kleines Volumen ergibt eine große Menge gebrauchsfertiges Scheibenwasser. Genau das macht die Linie ergiebig: Eine 250-ml-Flasche begleitet den Tank über viele Nachfüllungen, statt nach einer Tankfüllung leer zu sein.\u003c\/p\u003e\n\n\u003cp\u003eFreie Sicht ist dabei kein Komfortthema, sondern Sicherheit. Ein Insektenfilm, der bei tief stehender Sonne aufblitzt, kostet Sekunden Reaktionszeit. Genau in der Lücke arbeitet die Serie: Sie hält die Schmutzschicht so dünn, dass der Wischer sie wegzieht, statt sie quer über die Scheibe zu verschmieren.\u003c\/p\u003e\n\n\u003cp\u003eDie Serie ist bewusst schmal. Fünf Produkte, kein Sortimentsdschungel. Das Konzentrat fürs Wischwasser in drei Rezeptur-Stufen, ein gebrauchsfertiger Sommer-Mix und das Insekten-Gel für außen. Wer Sicht will, findet hier eine klare Antwort statt einer Wand aus Varianten.\u003c\/p\u003e\n\n\u003cp\u003eEingeordnet ins Markensystem ist CW1:100 die Scheiben-Zuständigkeit von Dr. Wack. Für Lack und Felge greift die Schwester-Linie \u003ca href=\"\/collections\/dr-wack-p21s\"\u003eP21S Felgenreiniger und Versiegelung\u003c\/a\u003e, für die laufende Autopflege die Allrounder aus \u003ca href=\"\/collections\/dr-wack-a1\"\u003eder A1 Autopflege-Linie\u003c\/a\u003e. CW1:100 bleibt bei der Scheibe.\u003c\/p\u003e\n\n\u003cp\u003eDiese Aufteilung ist kein Zufall, sondern Methode. Jede Dr.-Wack-Linie hat ein klares Substrat, und CW1:100 steht für Glas und Sicht. Wer das System einmal verstanden hat, sucht nicht lange: Scheibe heißt CW1:100, fertig. Das macht die Linie auch für Einsteiger einfach, die sich im Detailing nicht ständig neu orientieren wollen.\u003c\/p\u003e\n\n\u003ch3\u003eKonzentrat fürs Wischwasser stark verdünnt gefahren\u003c\/h3\u003e\n\n\u003cp\u003eDas Herz der Serie ist das Scheibenreiniger-Konzentrat. Es wird nicht pur benutzt, sondern stark verdünnt in den Wischwassertank gefüllt und dann über die Düsen auf die Scheibe gesprüht.\u003c\/p\u003e\n\n\u003cp\u003eIm Tank arbeiten die Tenside gegen genau die Filme, die Schlieren machen: Insekteneiweiß, Pollenfilm, Straßenstaub und Abgasruß. Das Konzentrat löst diese Schicht an, sodass der Wischer sie wegzieht, statt sie zu verschmieren. Ein Anti-Glare-Effekt sorgt dafür, dass bei tief stehender Sonne weniger Streulicht auf der Scheibe blendet.\u003c\/p\u003e\n\n\u003cp\u003eWichtig ist die Trennung zwischen Sommer und Winter. Die Sommer-Rezepturen sind auf Insekten und Sommerschmutz ausgelegt und ohne Frostschutz gefahren. Wer das \u003ca href=\"\/products\/dr-wack-cw1-100-super-scheibenreiniger-scheibenreiniger\"\u003eSuper Scheibenreiniger-Konzentrat\u003c\/a\u003e nutzt, mischt im Sommer mit Wasser an, im Winter gehört stattdessen ein frostsicheres Scheibenwasser in den Tank, sonst friert die Leitung bei Minusgraden ein.\u003c\/p\u003e\n\n\u003cp\u003ePraktisch heißt das ein klarer Saisonwechsel. Im Frühjahr, sobald die ersten Insekten kommen, wird der Tank auf die Sommer-Rezeptur umgestellt. Im Spätherbst, bevor die erste Frostnacht droht, kommt das frostsichere Winter-Scheibenwasser hinein. Wer den Tank im Herbst noch halb voll mit Sommer-Mischung fährt, riskiert eine eingefrorene Leitung und im schlimmsten Fall eine gerissene Pumpe.\u003c\/p\u003e\n\n\u003cp\u003eDie Stärke des Konzentrat-Prinzips ist die Ergiebigkeit über das Jahr. 250 ml ergeben ein Vielfaches an fertigem Scheibenwasser, das 5-Liter-Gebinde reicht für eine ganze Saison Vielfahrer. Pro Tankfüllung bleibt der Verbrauch im einstelligen Milliliterbereich, gemessen am Nutzen freie Sicht.\u003c\/p\u003e\n\n\u003cp\u003eAuch die Düsen profitieren. Reines Wasser im Tank setzt mit der Zeit Kalk und Algen an, die die feinen Spritzdüsen verstopfen. Das Tensid im Konzentrat hält die Leitung sauberer, sodass der Strahl gleichmäßig auf die Scheibe trifft und nicht einseitig wegspritzt. Das ist ein Nebeneffekt, der die wenigsten auf dem Schirm haben.\u003c\/p\u003e\n\n\u003ch3\u003eDrei Rezeptur-Stufen Classic Super und BIO\u003c\/h3\u003e\n\n\u003cp\u003eInnerhalb des Konzentrats gibt es drei Stufen, die sich in Reinigungskraft und Rohstoffbasis unterscheiden. Sie lösen dieselbe Aufgabe, nur unterschiedlich kompromisslos.\u003c\/p\u003e\n\n\u003cp\u003eClassic ist die Basis: ein hochergiebiges Konzentrat für den normalen Alltag mit moderatem Insektenaufkommen. Super ist die stärkere Stufe für Vielfahrer und Autobahn, wo im Hochsommer dicker Insektenfilm auf der Scheibe landet. BIO setzt überwiegend auf nachwachsende Rohstoffe und richtet sich an alle, die bei gleichem Sicht-Ziel auf die Rohstoffbasis achten.\u003c\/p\u003e\n\n\u003cp\u003eDie Wahl folgt der Fahrstrecke. Wenn du überwiegend Stadt und Landstraße fährst, reicht Classic. Wenn du im Sommer viel Autobahn fährst und abends die Scheibe voller Insekten hast, dann die Super-Stufe. Wenn dir die Rohstoffherkunft wichtig ist, dann BIO, mit etwas moderaterer Reinigungskraft als Super.\u003c\/p\u003e\n\n\u003cp\u003eAlle drei kommen als Konzentrat in kleinen Flaschen ab 25 oder 40 ml zum Probieren bis 250 ml für die Saison. Classic und Super gibt es zusätzlich im 5-Liter-Kanister für den Dauerbedarf. So lässt sich erst testen und dann groß nachkaufen, ohne die Stufe zu wechseln.\u003c\/p\u003e\n\n\u003cp\u003eDie Dosierung folgt dem Konzentrat-Prinzip, nicht einem starren Mischverhältnis für alle. Im Hochsommer mit dichtem Insektenfilm darf die Mischung kräftiger ausfallen, in der Übergangszeit reicht eine dünnere. Halte dich an den Aufdruck der jeweiligen Flasche, denn Classic, Super und BIO sind unterschiedlich stark eingestellt und vertragen kein pauschales Rezept.\u003c\/p\u003e\n\n\u003cp\u003eWer zwischen den Stufen unsicher ist, geht über die Strecke. Ein Wenigfahrer mit 8.000 km im Jahr ist mit Classic gut bedient. Ab 20.000 km und viel Autobahn lohnt Super, weil der Insektenfilm dort dicker und hartnäckiger ist. BIO ist die Wahl, wenn das Ergebnis stimmen soll, ohne dass die Reinigungskraft das einzige Kriterium ist.\u003c\/p\u003e\n\n\u003ch3\u003eFertig-Mix gegen Insekten-Gel zwei Wege\u003c\/h3\u003e\n\n\u003cp\u003eNeben dem Konzentrat stehen zwei Sonderwege in der Serie: ein gebrauchsfertiger Sommer-Mix für den Tank und ein Gel für außen. Beide ersetzen das Konzentrat nicht, sie ergänzen es für klare Anwendungsfälle.\u003c\/p\u003e\n\n\u003cp\u003eDer \u003ca href=\"\/products\/dr-wack-cw1-100-super-scheibenreiniger-fertig-mix-scheibenreiniger\"\u003eSuper Scheibenreiniger Fertig-Mix\u003c\/a\u003e kommt im 2,8-Liter-Gebinde und ist bereits angemischt. Er wird direkt in den Wischwassertank gekippt, ohne Wasser und ohne Dosierbecher. Das ist der bequeme Weg für alle, die im Sommer nicht rechnen wollen, dafür mehr Volumen pro Verpackung tragen als beim kompakten Konzentrat.\u003c\/p\u003e\n\n\u003cp\u003eDas Insekten-Entferner-Gel arbeitet außen am stehenden Fahrzeug, nicht im Tank. Seine Gel-Konsistenz haftet senkrecht an Frontscheibe, Außenspiegel und Scheinwerfer, statt sofort abzulaufen. So bleibt der Wirkstoff 1 bis 2 Minuten am eingetrockneten Insektenrest, weicht ihn auf und macht das Abspülen ohne Schrubben möglich.\u003c\/p\u003e\n\n\u003cp\u003eIn der Anwendung trägst du das Gel auf die trockene, abgekühlte Scheibe auf, nicht in praller Sonne. 1 bis 2 Minuten einwirken lassen, dann mit reichlich Wasser oder über die Waschanlage abspülen. Bei sehr dickem Insektenpanzer ist ein zweiter Durchgang ergiebiger als längeres Warten, weil das Gel sonst antrocknet und selbst Schlieren hinterlässt.\u003c\/p\u003e\n\n\u003cp\u003eSo entsteht die Arbeitsteilung: Das Konzentrat oder der Fertig-Mix hält die Scheibe während der Fahrt frei, das Gel räumt hartnäckige Reste am stehenden Auto weg, die der Wischer allein nicht löst. Erst zusammen decken sie den Insektensommer komplett ab.\u003c\/p\u003e\n\n\u003cp\u003eDer Fertig-Mix und das Konzentrat schließen sich nicht aus. Viele fahren das kompakte Konzentrat als Vorrat im Kofferraum für die Nachfüllung unterwegs und haben den 2,8-Liter-Mix zu Hause für die bequeme Tankfüllung griffbereit. So hast du für jede Situation das passende Gebinde, ohne dich auf einen Weg festzulegen.\u003c\/p\u003e\n\n\u003ch3\u003eWo CW1:100 im Markt steht ehrlich\u003c\/h3\u003e\n\n\u003cp\u003eDr. Wack CW1:100 ist solides, berechenbares Mittelfeld mit Made-in-Germany-Rezeptur, kein Effekt-Produkt. Die Stärke ist Verlässlichkeit über viele Tankfüllungen, nicht ein spektakulärer Einzeleffekt.\u003c\/p\u003e\n\n\u003cp\u003eGegenüber No-Name-Scheibenwasser aus dem 5-Liter-Kanister liegt der Unterschied im Insektenlöser und im Anti-Glare-Verhalten. Billig-Scheibenwasser verschmiert Insektenfilm bei Gegenlicht oft mehr, als es ihn löst. Das CW1:100-Konzentrat ist dafür gebaut, den Film anzulösen, damit der Wischer freie Sicht zieht.\u003c\/p\u003e\n\n\u003cp\u003eDie Grenze ist ebenso klar: CW1:100 ist kein Regenabweiser und keine Glasversiegelung. Es hält die Scheibe während der Fahrt frei, aber es lässt Regen nicht abperlen wie eine Fluorpolymer-Beschichtung. Wer eine dauerhafte Abperlwirkung an der Scheibe will, braucht zusätzlich eine echte Scheibenversiegelung. Das ist eine andere Produktklasse.\u003c\/p\u003e\n\n\u003cp\u003eAuch beim Insekten-Gel gilt eine Grenze. Es löst eingetrocknete Insektenreste an, ersetzt aber keinen Teerentferner für Bitumenspritzer und keinen Felgenreiniger für Bremsstaub. Für Eisen und Lack ist \u003ca href=\"\/collections\/dr-wack-p21s\"\u003edie P21S-Linie\u003c\/a\u003e zuständig, nicht die Scheiben-Serie.\u003c\/p\u003e\n\n\u003cp\u003eIm direkten Vergleich mit Wischwasser-Tabs oder Pulver punktet das flüssige Konzentrat bei der Mischsicherheit. Tabs lösen sich bei kaltem Wasser oft unvollständig auf und hinterlassen Rückstände, die wieder Schlieren machen. Das CW1:100-Konzentrat ist bereits flüssig und mischt sich sofort gleichmäßig, was die Anwendung berechenbarer macht.\u003c\/p\u003e\n\n\u003cp\u003eWer das ehrlich abwägt, bekommt eine klare Empfehlung. Für die laufende Sicht im Alltag ist die Serie eine verlässliche Standard-Wahl mit deutschem Rezeptur-Hintergrund. Für Spezialaufgaben wie dauerhafte Wasserabweisung oder grobe Lackverschmutzung braucht es zusätzliche, spezialisierte Produkte. CW1:100 will diese Aufgaben gar nicht abdecken und bleibt dadurch konsequent.\u003c\/p\u003e\n\n\u003ch3\u003eSo steigst du in die CW1:100 Serie ein\u003c\/h3\u003e\n\n\u003cp\u003eDer einfachste Einstieg ist eine Flasche Konzentrat plus das Insekten-Gel. Damit deckst du Fahrt und stehende Reinigung ab und brauchst keine weitere Scheibenpflege im Sommer.\u003c\/p\u003e\n\n\u003cp\u003eFür die Konzentrat-Wahl entscheidet die Strecke. Stadtpendler starten mit Classic, Vielfahrer und Autobahn mit Super, wer auf die Rohstoffbasis achtet mit BIO. Wer das Mischen scheut, nimmt im Sommer den 2,8-Liter-Fertig-Mix und spart sich die Dosierung ganz. Eine kleine 25-ml- oder 40-ml-Flasche reicht zum Testen, bevor du auf 250 ml oder den 5-Liter-Kanister gehst.\u003c\/p\u003e\n\n\u003cp\u003eBeim Gel richtet sich die Größe nach dem Insektenaufkommen. Die 100-ml-Flasche reicht für gelegentliche Reste, 500 ml oder 750 ml lohnen sich für Vielfahrer und die Hochsaison von Mai bis September. So musst du im Insektensommer nicht ständig nachkaufen.\u003c\/p\u003e\n\n\u003cp\u003eEin durchgängiges Set für die Saison sieht damit so aus: ein Konzentrat in der zur Strecke passenden Stufe für den Tank, dazu das Insekten-Gel in der zum Fahrprofil passenden Größe für außen. Wer das einmal im Frühjahr anlegt, kommt durch den ganzen Sommer, ohne kurzfristig nachkaufen zu müssen, wenn die Scheibe abends voll ist.\u003c\/p\u003e\n\n\u003cp\u003eUnterm Strich ist Dr. Wack CW1:100 die richtige Wahl, wenn du eine berechenbare Scheiben-Lösung aus einer Hand willst, die das ganze Jahr läuft und im Sommer den Insektenfilm im Griff hat.

A ready-to-use bug remover in gel form for the windscreen, headlights and the whole front end of a car. It stays put on vertical surfaces instead of running off. Not meant for the washer fluid, not for direct sun or hot surfaces, and not for bare aluminium without a spot test.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eCW1:100 \"Insect Remover Gel\"\u003c\/strong\u003e is a ready-to-use bug remover from Dr. Wack that loosens dried-on bug residue before you rinse it off. Bug residue is protein: on impact the body bursts, the water in it evaporates, and what's left is a protein layer that keys into the surface as it dries. That bond is exactly what the gel goes after.\u003c\/p\u003e\n\n\u003cp\u003eDenaturing is what happens to the protein here: it loses its folded shape and tangles into a hard, water-insoluble layer. The same thing happens to a fried egg, only this time on your clear coat. And just like with the fried egg: the hotter the surface and the longer it sits, the harder the residue sticks.\u003c\/p\u003e\n\n\u003cp\u003eAnionic surfactants and phosphates undo exactly that bond. They swell the tangled proteins and work their way between residue and surface until the grip lets go. You notice it because what looked glued on before runs off with the water when you rinse, without a towel having to go over it. And on a front covered in hard residue, rubbing is exactly the step that puts the swirls in.\u003c\/p\u003e\n\n\u003cp\u003eStill, the real trick isn't the chemistry, it's the consistency. A liquid cleaner runs down a raked windscreen in seconds and ends up in the scuttle panel instead of on the spot. The gel stays put like a damp compress: where it belongs, for as long as the reaction needs. In practice that means there's any dwell time at all on glass and bumpers in the first place.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCling time on the vertical.\u003c\/strong\u003e AUTO ZEITUNG tested all nine candidates in its bug remover test with a uniform 3 minutes of dwell time.

In between sits 500 ml as the standard size for one summer season with one car.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e We often see fronts that are spotless and still smear at the first rain. The cause isn't on the glass, it's on the wiper blade. That's where the same residue gets pressed in with every wipe cycle and hardens, and at the first rain the blade drags it across the fresh screen. So wipe both wiper blades with a cloth damp with gel before you rinse. Two wipers, two passes, twenty seconds.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eThe dwell time isn't on the bottle. Three minutes works.\u003c\/h3\u003e\n\n\u003cp\u003eIn the product information sheet Dr. Wack only says leave briefly to act and deliberately gives no number of minutes. AUTO ZEITUNG tested with 3 minutes and put the gel in second place. That's the reliable guide value.\u003c\/p\u003e\n\n\u003cp\u003eThe open instruction has a practical reason: how long it takes depends on how long the residue has been sitting. Freshly splattered bugs in summer still come off with water and a wet sponge after one night. After about forty-eight hours the protein layer has hardened and keyed into the clear coat so far that it won't go without chemistry. If the car was parked in blazing sun meanwhile, that window halves.\u003c\/p\u003e\n\n\u003cp\u003eSo with bug residue, time is the real active ingredient, twice over: once the time the residue has already been on the paint, and once the time the cleaner stays on it. The first you can only shorten by not waiting. The second is what the gel consistency buys you.\u003c\/p\u003e\n\n\u003cp\u003eThe routine itself is short. Turn the nozzle to spray, shake the bottle, apply the gel generously across the cool front instead of misting it. Going easy on the spray is false economy here, because the reaction needs liquid and a film that's too thin dries on within minutes.\u003c\/p\u003e\n\n\u003cp\u003eLeave it briefly, then rinse thoroughly with water and only then wash. For crusts that stay put, the product information sheet is clear about what to do: a sponge to help, wet, no pressure and no circular motion. A second application always beats waiting longer, because a gel that's drying on doesn't dissolve anything any more and just costs you an extra rinse.\u003c\/p\u003e\n\n\u003cp\u003eFinally, turn the nozzle back to stop. That's the leak protection, and anyone who keeps the bottle in the boot or door pocket knows after the first time why that setting exists.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/dr-wack-cw1-100-insekten-entferner-gel-insektenentferner_anwendung.jpg?v=1787867936\u0026amp;width=1400\" alt=\"CW1:100 Insect Remover Gel being sprayed onto bonnet and headlights\" loading=\"lazy\" decoding=\"async\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eThe test praises the cling and criticises the consumption\u003c\/h3\u003e\n\n\u003cp\u003eIn AUTO ZEITUNG's bug remover test from August 2025, the gel scored 77 out of 100 points and the seal Highly recommended. Praised were speed, thoroughness and the drip-free cling; criticised were the strong smell and high consumption.\u003c\/p\u003e\n\n\u003cp\u003eBoth criticisms are the flip side of the same property. Whatever stays on the vertical instead of running off also isn't spread thin, it's laid on thick. If you want to get a whole front wet, with screen, bonnet and bumper, the 500 ml bottle empties faster than you'd think. With two or three fronts per summer you won't notice; with weekly long-distance driving you will. Then 750 ml is the sensible size.\u003c\/p\u003e\n\n\u003cp\u003eTwo limits come from the product information sheet and aren't a formality. Don't use in direct sun or on hot surfaces: after two hundred kilometres of motorway, a dark bonnet is a lot warmer than the ambient air, and on a surface like that the gel dries on before it can swell the proteins.\u003c\/p\u003e\n\n\u003cp\u003eThe second limit concerns bare, unprotected aluminium, such as unpainted trim strips or polished parts. There, a test on an inconspicuous spot comes first. On painted, glazed and textured plastic surfaces, on the other hand, the manufacturer's approval applies without restriction.\u003c\/p\u003e\n\n\u003cp\u003eAnd the practical limit: the gel is designed for protein. Tree sap and tar aren't protein, and it won't help against them. If only the front is plastered with bugs after the motorway, this gel is the right tool. If sap from the roof, tar on the sills and a tired wax layer come on top, you're better off reaching for the \u003ca href=\"\/products\/dr-wack-a1-all-in-one-intensivreiniger-aussen-intensivreiniger\"\u003eheavy-duty cleaner for the pre-wash\u003c\/a\u003e, which clears the whole organic range. More alternatives are in the \u003ca href=\"\/collections\/insektenentferner\"\u003ebug removers\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eThe wiper reaches the screen. The gel reaches the rest of the front.\u003c\/h3\u003e\n\n\u003cp\u003eThe CW1:100 \"Insect Remover Gel\" is the only cleaner in its line that doesn't go into the washer fluid. The four screenwashes work from the inside via the washer system while you drive. This gel works from the outside, parked, right on the spot.\u003c\/p\u003e\n\n\u003cp\u003eThe division of labour is clean and answers the question of when you need what. If you're on the road and a smeary film builds up in the wiper area, a \u003ca href=\"\/products\/dr-wack-cw1-100-super-scheibenreiniger-scheibenreiniger\"\u003escreenwash concentrate for the washer fluid\u003c\/a\u003e belongs in the reservoir. It keeps your view clear, loosens fresh residue and prevents glare film against the light.\u003c\/p\u003e\n\n\u003cp\u003eIf, on the other hand, you're parked and the residue is hard, the gel comes in. The wiper reaches a rectangle on the screen, nothing in front of it and nothing beside it. No washer fluid in the world gets to the grille, the headlights or the mirror base. Together the two cover the front; on their own, each leaves half behind.\u003c\/p\u003e\n\n\u003cp\u003eThe difference shows after the first long night drive. In the wiper area the screen is streaky but see-through, because fresh washer fluid lands there every few minutes. Just above it, beyond the wiper sweep, the bug layer sits untouched, and the same layer covers the bonnet, grille and headlight glass. Those zones are the gel's turf.\u003c\/p\u003e\n\n\u003cp\u003eThat makes the gel for anyone who puts the miles in during summer and doesn't want to leave the front for weeks: country-road commuters, holiday drivers, motorhome and trailer use. As a pre-cleaner before the car wash it's half the battle, because otherwise the brushes push exactly the hard residue across the paint that they can't do anything about. If you drive your car in the winter half of the year and leave it parked in summer, you simply don't need it.\u003c\/p\u003e\n\n\u003cp\u003eOne last detail that says more about the manufacturer than any product description: on the product information sheet for this gel, right next to the application notes, there's a refund condition. Bottle at least two-thirds full, sent back with sufficient postage, receipt enclosed, address Baar-Ebenhausen.

The 1:100 in the name isn't a model code, it's the recipe on the label. One dosing chamber holds 25 millilitres and makes 2.5 litres of ready-to-use washer fluid, so the 250 millilitre bottle makes 25 litres. That's ten dosing chambers per bottle.\u003c\/p\u003e\n\n\u003cp\u003eThe film it goes after isn't a layer of dust. Bug remains, diesel soot, silicone and wax residue build up on the glass as a milky-looking, water-repellent layer. A glass sealant is water-repellent too, but it's built up evenly — it gives you clean beading. Glare film is the opposite: it scatters incoming light instead of letting it through. You'll notice it when every oncoming car dazzles you at night, even though the wipers just went over the glass.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe mixing ratio is in the product name.\u003c\/strong\u003e With the cap slightly unscrewed, squeeze the lower part of the bottle until the dosing chamber is full — that's the whole measuring system.

If you empty the dosing chamber straight into the tank and top up with water, you're not mixing — the concentrate just sits at the bottom. The first sprays foam up over-concentrated, the last ones are almost pure water. In the product information sheet, Dr. Wack recommends mixing the components in a separate container first. Empty 2.5 litre jug, 25 millilitres in, shake, pour — then what you dosed is what reaches the nozzle.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eOne dosing chamber holds 25 millilitres and makes 2.5 litres\u003c\/h3\u003e\n\u003cp\u003eCW1:100 \"Super\" screenwash is dosed at 1 to 100. One dosing chamber holds 25 millilitres of concentrate, making exactly 2.5 litres of ready-to-use fluid for the washer system.\u003c\/p\u003e\n\n\u003cp\u003eDose by feel and you pay twice. Too little concentrate, and the smear film stays as a haze the wipers just spread around. Too much, and the surfactants foam on dry glass, leave streaks and cost you two extra sprays to clear. The dosing chamber takes the guesswork out: unscrew the cap slightly, squeeze the lower part of the bottle until the chamber is full, unscrew the cap, pour in.\u003c\/p\u003e\n\n\u003cp\u003eThe work in the washer water is done by anionic surfactants. These are molecules with one water-loving and one grease-loving end that wedge themselves between the glass and the smear film and lift the film off. For you, that means the wiper doesn't just push the dirt around anymore, it takes it with it. That's exactly why the amount decides the result, not the number of wipes.\u003c\/p\u003e\n\n\u003cp\u003eWith the 40 millilitre single-dose bottle, there's no maths at all. At 1 to 100, 40 millilitres makes 4 litres of washer water, so one dose covers about one reservoir fill on most cars. That bottle lives in the glovebox as a top-up on the road; the bigger pack handles the planned dosing at home.\u003c\/p\u003e\n\n\u003cp\u003eThat the dosing chamber holds exactly 25 millilitres is straight from the product information sheet out of Baar-Ebenhausen. One fill, two and a half litres — that's all the mental arithmetic summer dosing asks of you. In canister format, the same sum looks like this: 5 litres of concentrate make around 500 litres of washer fluid, or 250 litres at winter strength.\u003c\/p\u003e\n\n\u003cp\u003eDr. Wack also says the cleaner extends the life of your wiper blades. There's no way to check that, but the mechanism is plausible: a wiper blade gliding over a loosened film works with less friction than one pushing dry dirt across the glass. The bigger lever, in our view, is never running the blade dry anyway — spray first, then wipe.\u003c\/p\u003e\n\n\u003cp\u003eFrom our own experience: water into the mixing container first, then the concentrate, then shake. The other way round, it foams over when you shake, and whatever ends up in the sink is missing from the tank. What sets the four \u003ca href=\"\/collections\/dr-wack-cw1-100-scheibenreiniger\"\u003escreenwashes in this range\u003c\/a\u003e apart comes down to exactly one number — the mixing ratio.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/dr-wack-cw1-100-super-scheibenreiniger-scheibenreiniger_anwendung.png?v=1787867946\u0026amp;width=1400\" alt=\"Dosing chamber of CW1:100 Super screenwash being emptied into the open washer fluid reservoir\" loading=\"lazy\" decoding=\"async\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eThe Super boosts your antifreeze — it can't replace it\u003c\/h3\u003e\n\u003cp\u003eCW1:100 \"Super\" screenwash doesn't lower the freezing point. In winter it goes into a finished antifreeze mix on top, dosed at 1 to 50 instead of 1 to 100.\u003c\/p\u003e\n\n\u003cp\u003eThe order is in the product information sheet and still rarely followed: antifreeze concentrate first, then fresh water, then the Super. Four dosing chambers, i.e. 100 millilitres, per 5 litres of finished antifreeze mix. If you put the cleaner into the empty canister first, it only gets mixed in by chance as you fill up.\u003c\/p\u003e\n\n\u003cp\u003eIt gets expensive with antifreeze concentrates rated down to minus 60 degrees. Those must never meet the Super undiluted. Dr. Wack requires you to dilute the concentrate with fresh water to minus 30 degrees at most first, and only then add the cleaner. The sheet doesn't give a reason. We stick to it anyway, because a clogged washer jet in January is no small thing.\u003c\/p\u003e\n\n\u003cp\u003eThe reason tap water is good enough here is the anti-limescale formula. In hard-water areas, calcium is what gradually grows the fine nozzle opening shut over the years. The formula binds it before it can settle — which is why Dr. Wack specifies fresh tap water, not distilled. Day to day, that means you skip the jug from the DIY store and mix at the tap.\u003c\/p\u003e\n\n\u003cp\u003eThe second limit is in front of the windscreen. No washer fluid dissolves dried-on bug shells on the bonnet, grille and headlights, because there's no dwell time — the wiper is on the glass for seconds, not minutes. If the film builds up while you're driving, the Super is the right tool. If the remains dry on while the car is parked, you need an \u003ca href=\"\/products\/dr-wack-cw1-100-insekten-entferner-gel-insektenentferner\"\u003einsect remover that clings as a gel\u003c\/a\u003e on the surface, one that stays put instead of running off.\u003c\/p\u003e\n\n\u003cp\u003eIn issue 22 of 2022, Auto Bild put the Super up against eight other screenwashes.

Full marks of 15 for material compatibility, 56 out of 80 points for pure cleaning power.\u003c\/p\u003e\n\n\u003cp\u003eTranslated: if maximum cleaning power trumps everything for you, there are stronger contenders in the field. If you don't want anything to happen to paint, rubber seals or plastic headlight lenses, you're in the right place — and according to the manufacturer, the formula was developed for exactly those parts.\u003c\/p\u003e\n\n\u003ch3\u003eDose it yourself and you stop paying for water\u003c\/h3\u003e\n\u003cp\u003eA 1:100 concentrate doesn't haul water around. 250 millilitres of CW1:100 \"Super\" screenwash become 25 litres of ready-to-use fluid; the other 24.75 litres come out of the tap at home.\u003c\/p\u003e\n\n\u003cp\u003eWhich pack pays off depends less on the car than on how you drive. If you do lots of motorway miles, you'll empty the washer reservoir much faster in bug season than the rest of the year — that's what the 250 millilitre bottle with dosing chamber is built for. The 40 millilitre single-dose bottle is the glovebox top-up. The 5 litre canister pays off from the second car in the household.\u003c\/p\u003e\n\n\u003cp\u003eA second consumer is listed in the product information sheet and usually gets lost in the windscreen discussion: the headlight washer system. Cars with pop-out washer jets on the headlights draw from the same reservoir. That doesn't change the dosing, but it does change consumption — if you trigger the system regularly in winter, the reservoir empties much faster and you're better off with the canister than the single-dose bottle.\u003c\/p\u003e\n\n\u003cp\u003eIf you want to mix yourself and you've got a tap anyway, the concentrate is the leaner route — on the shelf, in the boot and in the amount of plastic per litre of washer fluid. If you want the canister ready-mixed in the boot because there's no water on the road, grab the \u003ca href=\"\/products\/dr-wack-cw1-100-super-scheibenreiniger-fertig-mix-scheibenreiniger\"\u003eready-to-use pre-mix\u003c\/a\u003e. That's not a ranking, it's a decision about where the water gets added.\u003c\/p\u003e\n\n\u003cp\u003eThe first time round, measuring feels more of a faff than emptying a ready-made jug. That's normal. After two or three fills you've got the hang of it, and the dosing chamber becomes what it is — the measuring cup already built into the bottle.\u003c\/p\u003e\n\n\u003cp\u003eThe tip no label gives you: don't wait for the first frost forecast to switch to winter dosing. If you move to 1 to 50 in October, while late-summer bug remains are still on the glass, you get the double dose exactly when it has the most work to do. And in January the antifreeze mix has long been sitting correctly in the reservoir, instead of being thrown together on the driveway at minus five.\u003c\/p\u003e","brand":"Dr. Wack \"CW1:100\"","offers":[{"title":"250ml","offer_id":54707201835343,"sku":"D1-DRW-1745","price":12.99,"currency_code":"EUR","in_stock":true},{"title":"40 ml","offer_id":54707201868111,"sku":"D1-DRW-1749","price":3.99,"currency_code":"EUR","in_stock":true},{"title":"5 Liter","offer_id":54707201900879,"sku":"D1-DRW-1743","price":126.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/dr-wack-cw1-100-super-scheibenreiniger-scheibenreiniger.png?v=1787867479"},{"product_id":"dr-wack-cw1-100-super-scheibenreiniger-fertig-mix-scheibenreiniger","title":"CW1:100 \"Super\" screenwash, ready-to-use","description":"\u003ch2 id=\"speakable-headline\"\u003eClear view without mixing, straight from the jerry can\u003c\/h2\u003e\n\u003cblockquote id=\"speakable-summary\"\u003e\u003cp\u003e\u003cem\u003eThe CW1:100 Super screenwash ready mix is a ready-to-use summer cleaner for the washer reservoir.
