Would Poorboy's S&W or QEW be useful as pretreatment to remove the bulk of the surface soil and grime from the paint surface before washing? I would like to use something that would loosen the grime's grip on the surface and allow a water nozzle spray to wash off the majority of the dirt.
I've tried car wash shampoo in several concentrations, but I haven't been successful at removing much of anything without using a wash mitt. I'm not trying to take a shortcut washing my vehicle, my primary motivation is to reduce surface contamination before rubbing the paint with the wash mitt and thereby reduce the risk of marring the paint.
Any other suggestions?
