Do these remove the white clay residue from using a wax on the plastic inadvertently? I used the kit the dealer gave me and it made the plastic turn a whitish gray color. Ceramic was applied to the plastics too, so I assumed the wax would be fine on that. I tried NuVinyl, and another vinyl cleaner and it only lasts a few weeks at the most. Dealers service person told me to "steam it out". I have no clue how to go about that.
