Before finding Autopia and AG I used the kit that bestop makes for the top. It`s 3 separate chemicals, I believe one to to protect the top, one to clean, and one specifically for the Windows. But i think one or both of the top chemicals aren`t supposed to come in contact with the windows...kind of a pain. I don`t use the cleaners as much as I should usually just stand on the tire and use the wash mit with some soap. I am curious if something like hydro2 would work.
