Odd man out here on cleaning. Do a hasty clean dry brushing with a cheap bristle brush. Scrape out the imbedded dirt and grass, pine needles, etc. with shaped wooden dowel rod or flat wood "popsicle" sticks.
Deliberate clean with fluids only for repair or replace. Caveat being soapy water wash and air dry for the body. Followed by a thin application and dry buffing with Meguiar's PLASTX on the exposed body surface.
Running nitro, I'd use a blast of compressed air for quick clean because of the pasty oil/dirt residue prevalent with nitro. Seldom if ever use compressed air on electric.
Only time my trucks or buggies are showroom clean is right after a build or buy or when selling. Rest of the time, they're 'good nuff.'
