After you've scrubbed down the entire car, give it a quick once-over with your sudsy wash mitt. This will help avoid water spots -- most car wash soaps have an anti-spotting agent. (Dish soap doesn't, another reason not to use it.) Remember to rinse and reload the mitt frequently and work from the top down.
