As above, unless you use entirely abrasive compounds to polish the surface, you're undoing your hard wOrk. Most of these other polishes have fillers to fill in swirls. Washing will just remove them.
It shouldn't take you forever to do. I reckon you could wash, clay, dry, polish and wax in about four hours. Get up early to do it if you have to. Sunrise is around 0600 these days.
