Meg's Deep Crystal wash isn't supposed to leave anything behind, but is not a "premium" soap. Gold Class has "paint conditioner" that leaves a glossy surface, but cleans well.I have been having issues with my soap. Mr. Pink from chem guys for some reason leaves a bit of a residue when it dries. Also, I have tried maxi suds and it destroys my paint with leftover residue…Could it be my soft water causing the soap to leave a residue?? Could it just be the soap not being of high quality? I'm on the market for a good soap that won't leave behind any residue/washes completely off. Any suggestions??
Might want to look into Matte finish soaps. They should leave a min. of residue.
