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 to bare steel too, ideal for owners of older vehicles which may have stone chips or exposed areas of mild steel.

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. auto-wash is quite simply the best car shampoo out there.
