Getting a bit confused. I've been cleaning cars for decades and have always used a sponge!. Am I risking the paint work then or not in your opinions? What I tend to do is this; Using my jet washer I soak the entire car with water and remove loose dirt with the lance. Then I use a snow foam all over the vehicle. Rinse off, followed by going over the whole car with a sponge using the two bucket method ~ one with soap/warm water & the other to clean the sponge. Then I use a chamois clothe to dry the whole car. Opinions please, thanks.
