Bilt Hamber auto-wash is an Ultra-Concentrated, Award-Winning Car Shampoo.
Discover the cleaning power of Bilt Hamber auto-wash, an ultra-concentrated vehicle shampoo with an outstanding 1:2000 dilution ratio. Just 5ml in a 10L bucket is all you need to achieve a rich, effective lather, giving you up to 100 washes from a single 500ml bottle.
Formulated without salts, waxes, perfumes or colourants, auto-wash delivers a pure clean that rinses off easily and leaves nothing behind to dull your finish. This additive-free formula also means there is less residue to remove before polishing, saving you both time and effort.
Powerful yet gentle – ideal for classic and modern cars
auto-wash isn’t just any shampoo. Its anti-corrosion properties provide class-leading long-term protection for bare steel, making it a trusted choice for owners of vintage and classic cars with stone chips or exposed areas of mild steel. The same anti-corrosion technology helps protect modern cars too, where seams and folds can trap corrosive salts carried by some detergents.
By using advanced surfactants, auto-wash gently lifts dirt, grime and road film away from the paintwork, reducing the risk of scratches and swirl marks during washing. The high foam level means dirt is safely encapsulated and rinses away cleanly.
