Adam's Polishes Car Wash Shampoo (2-Pack) - pH For Snow Foam Cannon, Foam Gun, Pressure Washer & 5 Gallon Wash Bucket, Powerful Spot Free, Safe On Car Wax & Ceramic Coating

Pricey for what you get but I guess it better for your car that some of the cheap brands (?).

I’ve used Koch Gentle Snow Foam and Meguiar’s Gold Class car shampoo before using this. The Adam’s soap has the least lubricity compared to the car wash products I’ve used. While the Meguiar’s Gold class shampoo has noticeably more lubrication, the Koch Chemie GSF has more dissolving power as a foam.

Outstanding product. Very little goes a long way and cleans very very well.

Great thing about this shampoo is the cost and the fact that you can use it in the sunlight, unlike many more expensive car shampoos.

Good stuff !
