A pH-neutral car shampoo from the Q²M line that washes with thick foam and high lubricity, without stripping ceramic coatings, waxes or sealants. It's not the tool for baked-on bug splatter, tar or brake dust on paint — those need dedicated cleaners.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eGYEON Bathe\u003c\/strong\u003e is a pH-neutral car shampoo from GYEON that lifts road grime and loose dirt at a 1:500 dilution without chemically attacking the protection layer on your paint. GYEON Bathe is a maintenance shampoo for coated cars — the pH sits at 6, the formula runs on mild surfactants and throws a dense foam blanket that builds up just as well in the wash mitt as out of a foam lance.\u003c\/p\u003e\n\n\u003cp\u003eThat heavy foam isn't there for show, it's part of how the wash works. The foam holds the lifted dirt in suspension before it can drop back onto the paint. The slickness between mitt and paint cuts micro-scratches far harder than plain dish-soap formulas ever will.\u003c\/p\u003e\n\n\u003cp\u003eThat's exactly where it splits from cheap supermarket shampoo. With those, the cleaning punch is aggressive and strips your existing wax along with the dirt. With GYEON Bathe the glide does the gentle work, and your coating or wax stays untouched.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_gyeon-q2m-bathe-autoshampoo_hero.jpg?v=1776536845\" alt=\"GYEON Q²M Bathe car shampoo on a bench next to a black coupé\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003epH 6 — your coating and your wax stay put.\u003c\/strong\u003e The formula sits in the neutral range and lifts neither ceramic coatings (GYEON MOHS, say), sealants nor hard waxes. You wash a coated car across the full life of the coating without ever having to plan a shampoo swap. With alkaline shampoos the hydrophobic performance drops measurably after every wash — with a pH-neutral wash it doesn't.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBig foam plus slickness.\u003c\/strong\u003e 15 to 20 ml in a 10-litre wash bucket builds a stable foam blanket that stands for 20 to 30 minutes. More important than the looks: the foam carries dirt particles mechanically away from the paint, and the slickness drops the friction between mitt and clear coat. That's your measurable scratch protection on the two-bucket workflow.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1:500 dilution — 1 litre gets you about 50 washes.\u003c\/strong\u003e At 15 to 20 ml per bucket, the 1-litre bottle gives you between 50 and 66 full car washes — that works out at 0.45 to 0.60 EUR per wash depending on how often you wash. The 4-litre jug drops the per-litre price again and pays off from the second car or across a season of weekly washing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDay-to-day from Detailing1:\u003c\/strong\u003e The most common slip with GYEON Bathe is dosing by eye. Tip a \"decent splash\" into the water and you're quickly at 40 to 50 ml in the bucket, washing at double strength. The foam doesn't get any better for it, the rinse-off turns into a chore, and you get white residue left around the trim. Measure 15 to 20 ml into warm water at 30 to 40 °C with a measuring cup. Warm water fires up the surfactants faster and you can hear the foam holding better — the one step that matters most and the bottle never mentions on the back.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e1:500 dilution. Warm water. Two-bucket.\u003c\/h3\u003e\n\u003cp\u003eYou mix \u003cstrong\u003eGYEON Bathe\u003c\/strong\u003e at a 1:500 dilution — that's 15 to 20 millilitres to a 10-litre wash bucket. Pre-rinse the car with clean water first to flush off loose dust and grit before the mitt ever touches the paint. This step is your single biggest scratch protection before the wash itself — no shampoo on earth makes up for quartz dust ground into the clear coat.\u003c\/p\u003e\n\n\u003cp\u003ePut the warm water in the bucket first, then pour the Bathe in — not the other way round, or the dose bubbles over and the strength climbs out of your control. Wash panel by panel, top down from the roof.\u003c\/p\u003e\n\n\u003cp\u003eBetween panels, rinse the mitt in the second bucket of clean water — that's the \u003ca href=\"\/collections\/autoshampoo\"\u003etwo-bucket workflow\u003c\/a\u003e, which pulls the dirt out of the mitt before it goes back on the paint.\u003c\/p\u003e\n\n\u003cp\u003eBathe runs reliably through a foam lance too, though it isn't built as a straight pre-wash foam. Reckon on a dilution of around 50 ml to 1 litre of lance mix and give the foam 3 to 5 minutes of dwell time before you rinse.\u003c\/p\u003e\n\n\u003cp\u003eFoaming up in direct sun makes no sense — on hot paint the foam dries out in minutes and leaves water spots behind. Aim for outdoor temperatures between 10 and 20 °C or a shaded garage.\u003c\/p\u003e\n\n\u003cp\u003eTo finish, rinse thoroughly with clean water until no more foam runs off, and dry straight away with a \u003ca href=\"\/products\/gyeon-q2m-silkdryer-evo-trockentuch\"\u003esoft drying towel\u003c\/a\u003e. Air-dried cars pick up water spots from the dissolved minerals — especially in hard-water areas, drying within 5 minutes of the rinse is a must, not a suggestion.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_gyeon-q2m-bathe-autoshampoo_anwendung.jpg?v=1776536844\" alt=\"GYEON Q²M Bathe in use, two-bucket foam wash\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eBathe washes. Bugs and tar, it doesn't.\u003c\/h3\u003e\n\u003cp\u003eOn regular road grime, dust, pollen and salt residue Bathe works reliably — that's its home turf. The pH-neutral formula is built squarely for the recurring wash, not the deep clean after three months of city traffic with no care. That's its strength and its limit in one.\u003c\/p\u003e\n\n\u003cp\u003eHeavily baked-on bug splatter, tar spots and tree sap, Bathe won't shift reliably. The neutral surfactants simply don't have the chemical bite to break down chitin or bitumen.\u003c\/p\u003e\n\n\u003cp\u003eIf you've got bugs on the bonnet, work with a dedicated bug remover like the \u003ca href=\"\/products\/gyeon-q2m-bugandgrime-insektenentferner\"\u003eQ²M Bug\u0026amp;Grime\u003c\/a\u003e as a pre-wash step. Loosen it alkaline first, let it dwell, rinse, then run the full wash with GYEON Bathe.\u003c\/p\u003e\n\n\u003cp\u003eAgainst baked-on brake dust on paintwork too (after car parks by rail lines or building sites) Bathe is powerless — that's a job for an iron remover like GYEON Q²M Iron. Same goes for water spots from limescale tap water: Bathe washes over them but doesn't take them off. Managing expectations is the key thing here — this is a weekly maintenance shampoo, not a decontamination tool.\u003c\/p\u003e\n\n\u003cp\u003eTo set it apart from its big brother Q²M Bathe+: the Bathe+ also packs SiO₂ and lays down a hydrophobic protection layer with every wash that holds for around 6 to 8 weeks.\u003c\/p\u003e\n\n\u003cp\u003eIf you want to wash a freshly coated car regularly without boosting on top, the regular GYEON Bathe is plenty. If you've got no coating but still want beading and a touch of extra protection, the Bathe+ is the better call. Both are pH-neutral and coating-safe — the choice comes down to the side effect you want, not the cleaning power.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_gyeon-q2m-bathe-autoshampoo_ergebnis.jpg?v=1776536845\" alt=\"GYEON Q²M Bathe foam blanket close-up on black paint\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eFor coating owners who wash every week.\u003c\/h3\u003e\n\u003cp\u003eBathe is the right call for anyone running a ceramic coating or a long-life hard wax on the paint who doesn't want to undo that protection across its full life. No exceptions, no debate — an alkaline shampoo eats into any coating measurably within a handful of washes. So if you've put money into GYEON MOHS, Q² One or a hard wax, you wash pH-neutral. That's not a recommendation, it's a technical must.\u003c\/p\u003e\n\n\u003cp\u003eFor light washers (once a month or less) Bathe is solid but not essential. Wash rarely and you usually carry heavier dirt per wash, and you'll do better with an alkaline pre-wash plus a neutral main shampoo. Then Bathe becomes the second step of a two-stage process — useful, but no substitute for a dedicated deep-clean shampoo like Q²M RestartWash.\u003c\/p\u003e\n\n\u003cp\u003eDay-to-day at Detailing1 we run Bathe paired with a \u003ca href=\"\/products\/gyeon-q2m-silkdryer-evo-trockentuch\"\u003esoft microfibre dry\u003c\/a\u003e and a solid wash mitt. That's the full care workflow for coated cars — pre-rinse, foam lance, two-bucket hand wash, clean rinse, dry within 5 minutes. Under 25 minutes per car, every week.\u003c\/p\u003e\n\n\u003cp\u003eOn bottle sizes: the 500 ml bottle is the compact way in for around 25 to 33 washes — ideal for checking the scent and the foam. The 1-litre bottle is the standard size for one household and lasts close to 12 months at a weekly wash. The 4-litre jug pays off from the multi-car household or commercial use and brings the per-litre price down noticeably.\u003c\/p\u003e\n\n\u003cp\u003eStore frost-free and use up within 12 months of opening — after that the foam stability drops off noticeably. The biggest difference between GYEON Bathe and cheap shampoos stays simple in the end: you wash your car 50 times from one bottle, and your coating survives all 50 washes unharmed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_gyeon-q2m-bathe-autoshampoo_lineup.jpg?v=1776536845\" alt=\"GYEON Q²M Bathe sizes 500 ml, 1 litre, 4 litre\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n","brand":"GYEON","offers":[{"title":"1000 ml \/ 1 liter","offer_id":57031642186063,"sku":"D1-GYEON-Q2MBATHE1000","price":40.8,"currency_code":"USD","in_stock":true},{"title":"500ml","offer_id":57031642218831,"sku":"D1-GYEON-Q2MBATHE500","price":21.76,"currency_code":"USD","in_stock":false},{"title":"4 liters","offer_id":57031642251599,"sku":"D1-GYEON-Q2MBATHE4000","price":108.83,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/gyeon-q2m-bathe-autoshampoo.png?v=1771067828","url":"https:\/\/detiiling1.com\/products\/gyeon-q2m-bathe-autoshampoo","provider":"Detailing1","version":"1.0","type":"link"}
