It's part of the prerinsing stage of the wash. You foam the car down and let the foam dwell allowing any loose dirt to be removed before going over the paint with a wash mitt. It's easy, looks cool, and really helps in minimizing scratches IMO. Ever since I started foaming my car, the car has definitely come out much cleaner in the end than it did before
