GYEON Q²M Bathe+ (Plus) Ceramic-Effect Car Shampoo 500ml

Wash and seal in one step – GYEON Q²M Bathe+

What is GYEON Q²M Bathe+? GYEON Q²M Bathe+ is a SiO₂-enriched premium car shampoo that tops up the hydrophobics on your existing coating while you wash – every wash brings back stronger beading and deeper gloss.

A car shampoo that refreshes your coating's protection while you wash – that's the idea behind GYEON Q²M Bathe+. The Plus version of the well-known Q²M Bathe carries SiO₂ ceramic particles that work into the coating's surface as you wash and wake the lotus effect back up. The result: after every wash with Bathe+, water beads like it does on a freshly sealed car – no extra step needed.

• SiO₂ ceramic particles top up the hydrophobics on every wash. Q²M Bathe+ carries active SiO₂ particles that boost water repellency the moment they hit a ceramic coating or a polymer sealant. After each wash the paint beads harder – a visibly stronger lotus effect with no extra work.
• Stretches the life and performance of your existing coating. Every wash with a plain shampoo chips away at a coating a little. Q²M Bathe+ flips that around: it feeds the coating on every wash instead of wearing it down. Coatings measurably last longer when you run Bathe+ as your maintenance shampoo.
• Deepens the gloss – you see it after every wash. The SiO₂ particles in Q²M Bathe+ don't just drive the beading, they also lift the optical gloss of the paint. The finish looks deeper and wetter after the wash than it would with a standard shampoo.

Day-to-day from Detailing1: Q²M Bathe+ does its best work on cars that already carry a ceramic coating or a polymer sealant. On completely bare paint the SiO₂ effect is a lot weaker. For the cleanest result, knock back bugs and stubborn grime first with Q²M Bug&Grime, then wash with Bathe+ – and watch the beading kick in the moment you rinse.

SiO₂ washing: how Q²M Bathe+ rethinks coating care

Building SiO₂ ceramic particles into a car shampoo is a fairly young move in detailing – and GYEON Q²M Bathe+ shows why it caught on. As you wash, the SiO₂ particles come into direct contact with the paint and whatever protection is already on it. The washing action spreads them evenly and boosts the hydrophobic behaviour of the coating. Once you rinse, the surface beads noticeably harder than it did before the wash. The effect builds up over several washes and keeps a coating fresh far longer than a plain shampoo would.

Q²M Bathe+ – which cars and which situations?

Q²M Bathe+ works best on cars running a ceramic coating (e.g. Q² Mohs EVO, Q² One EVO or Q² Syncro EVO) or a polymer sealant. On a freshly sealed car, Bathe+ stretches the coating's life considerably. For cars with no coating at all, we'd point you to the regular Q²M Bathe instead, which is plenty for bare surfaces. Cars wearing PPF, on the other hand, should go with Q²M PPF Wash.

The ideal wash routine with Q²M Bathe+

For the best result with Q²M Bathe+ we'd run it in this order: pressure-rinse to knock off the loose grit, then a pre-foam with Q²M Foam for a touchless first pass, then the contact wash with Q²M Bathe+ using the two-bucket method, a thorough rinse and a dry. If you want to top the protection up even further after the wash, lay Q²M WetCoat onto the wet car – the Bathe+ and WetCoat combo is hard to beat for a quick protection refresh.

Q²M Bathe vs. Bathe+ – when is the upgrade worth it?

Both shampoos are excellent – the pick comes down to the car and what you want out of the wash. Q²M Bathe is the efficient everyday shampoo for a proper clean, no extras. Q²M Bathe+ is the one we'd recommend for cars with a ceramic coating or sealant – the upgrade pays off for anyone who wants to squeeze the most life out of their coating and keep the lotus effect topped up after every wash. Price-wise Bathe+ sits a touch higher, but its double duty (cleaning + coating care) makes it the more efficient buy.

Our pick: the best shampoo for coated cars

GYEON Q²M Bathe+ is our first call for any car with a ceramic coating. It takes a lot of the fuss out of coating care: no separate maintenance step after the wash – the lotus effect gets topped up on its own. To round it out: Q²M Bug&Grime for the pre-wash, Q²M Cure for the monthly coating refresh, and Q²M WetCoat for a wet-seal after a heavy clean.
