Bilt Hamber Auto Wash (500ml)

Auto-Wash is a new technology, highly powerful, environmentally friendly car shampoo, formulated to allow you to effortlessly and effectively clean your paintwork before waxing.

Auto-Wash is anti-corrosive and suitable for bar steel also, ideal for owners of older cars which may have stone chips of exposed areas of mild steel. This is also an advantage in modern cars, where the entrapment of corrosive elements carried by some detergents in folded seams accelerates the corrosion. 

Auto-Wash is very highly-concentrated, meaning that much less solution is needed to add to the water. Not only do you save money, but the added benefit of this is simple - there is less matter to remove from your paintwork prior to polishing.

Auto-Wash will chamois off with ease to leave a perfectly clean body, ready for further treatment. In fact, a single shampoo can be carried out with just a single teaspoon of auto-wash, meaning one wash will cost you around 16p.

Auto-Wash uses powerful surfactants to create a high foam level. This simply means that particulate matter is lifted away from the paint, where it can be safely removed with reduced risk of scratching or damage to your car's paintwork.

How to Use

Auto-Wash is a highly concentrated car shampoo, just a 5ml spoonful (1 teaspoon to a 10L bucket) is sufficient.

Its low viscosity ensures it pours easily, the measured amount should be emptied into a clean bucket before adding the warm water, thus creating a thick lather for paintwork cleaning.

Auto-Wash can be used neat as a pre-wash spot cleaner, using a clean swab for removal of very stubborn oily films.
