Bubbling Suds Shampoo
Hi-Temp's "Bubbling Suds" is a great choice. It's a thick, high-foaming cleaning machine, but its low pH of 8.5 WILL NOT strip paste waxes or sealants.
Bubbling Suds is a powerful formula that dissolves road film and dirt, or any grime that dares to contaminate your vehicle. Use it with your favorite wash mitt, natural sponge, or boar's hair shampoo brush.
Just 2 oz. per gallon creates enough suds to last the entire wash. (Nothing is worse than running out of suds!)
