Many people have also expressed concern about the aggressiveness of the soap used at touchless washes. Will it dull my paint? Will it strip my wax or sealant? The answers are no, and no. I’ve been taking my cars thru touchless washes for the last few years and have encountered no problems to date. My klasse sealant glaze always sheets water the first time I hand wash my car in the spring. This tells me that there is still SG left on my paint. The fact that there is still a thin film of dirt present on my paint after existing the wash is another indicator that the soap is not as aggressive as believed.
