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!

In my testing I found that I was able to make excellent foam with 2oz of the Mega Foam soap and 4oz of the Original formula. Unfortunately the Ultra formula took the most soap for comparable suds, over 6 ounces! This was used with Adam's Foam Cannon and my pressure washer.
When I tested pH I found that the Ultra Foam was the most alkaline, coming in at 8.5. The Mega Foam and regular Car Shampoo seemed fine at 7.8 and 7.5. I used a 3 to 1 ratio of water to soap to do this testing, 10ml of soap and 30ml of water. You can use algebra to figure out the pH you would get depending on your actual dilution ratio.
In my panel testing I found that the Mega Foam Car Soap seemed to strip my Car Guys Hybrid Wax the fastest. It's not a definitive test by any means, but looking at the data sheets from Adam's it seems like there is an organic solvent and isopropyl alcohol in their Mega soap. On the other hand the original Car Shampoo did very well with 7 washes. The Ultra didn't fair as well with 5.
