Why not let Mother Nature do the work for you, then? Fill a
spray bottle with diluted dishwashing detergent, park the car
outside and spray it down with the detergent just before the skies
open up. Then, when it stops raining, go back outside and dry the
vehicle with a towel.
That's usually how I wash my year-round "winter beater." My summer
car, however, gets the royal treatment with a hand wash and polish.
