Mothers California Gold Car Wash We created Car Wash with a careful balance of powerful cleaning and exacting care. Now you can wash your car thoroughly while protecting your wax. It’s not just about bubbles—various dishwashing liquids and “soaps” can harm your wax. Our Car Wash is strong enough to wash away dirt, road film, bugs, bird droppings, airborne pollutants and other grime, without removing wax or dulling the paint. Mothers pH balanced, super-sudsy cleaner also resists water spotting. Mixing: approx. 30ml of Mothers California Gold Car Wash per 4L of water.
