I've been cleaning my cquartz coated wheels (and tyres) with high alkaline (Bilt Hamber Surfex HD) at 10:1 dilution which is still around PH 14, and it has completely killed the coating. Clearly I'm using way to aggressive a cleaner. I'm wondering what I should be using? Should I just stick to reset, and occasionally ironx for decontamination? Is it worth spending more on snow soap? Should I use something else?

I'm about to re-coat with DLUX and would like to alter my wash routine so I don't have to do this again for a while!
