In a full detail, do you wash again after claying/nanoskin before you start polishing? Or do you just wipe off lube with clean MF towels as you clay and then go straight to polishing? Or something else?
I rinse off the vehicle with another hose rinse and then dry completely before polishing including blowing out all the cracks, crevices, emblems, grill, headlights etc. I use a mixture of car wash soap as clay lube and simply make sure all of that is off and not dried on the paint.
if there is a lot of residue or something that you think will interfere with the polish, i spray QD strength ONR on a quartered MF and wipe, then flip towel and dry. or do that with Opti-Clean. no need to go crazy.
Since I use a quick detailer as a lubricant, I don't follow up with a wash. I only do after compounding/polishing to remove any leftover dust from the polish.
