Adam's Polishes has three shampoos on the market; Their original Adam's Car Shampoo which is the basic one, Adam's Ultra Foam which is supposed to be a step up for foam guns and cannons, and their new Adam's Mega Foam which is supposed to make the best foam gun and foam lance foam. I've used Adam's Car Shampoo for years and it is what I use in all my wax tests. However, is it the best for making big foam and is it the safest on wax? Is it really pH neutral? We find out in today's testing!
