thats exactly how i used to detail my car along w/ everyone elses during college. just get your bucket ready w/ soap already in there. put the money in and have it on the wash function (not rinse), go over your entire car to loosen up the dirt and get it wet. that should only take like 90 secs or whatever. then w/ the rest of the time left use it to fill up your bucket and get your sponge wet.

once the water stops, scrub down your entire car. i could thoroughly go over my entire car in literally 5 mins or less w/o missing a spot. then once youre done, put in another few quarters and rinse it off.

dry w/ cali water blade and the absorber and youre done. time to take it back for waxing and the rest of the detail crap.
