The instructions on the label doesn't say much. 1. Mix 2. Apply, one section at a time 3. Wipe Dry In which phase do I do the actual cleaning of dirt and how much pressure do I use? Do I need to run the sponge and cover the area liberally with QEW, then make another pass with the sponge before I apply any real pressure? How is it any different from other detergent? I made a gallon of wash solution using recommended dilution ratio of 1 oz per gallon and it feels and looks just like water. Are you sure this isn't going to cause as much scratch as doing it using plain water??
