Professional window cleaners rarely wipe their blade after each pass because you wear the rubber down twice as fast if not more.

Your streaking problem could be your solution, or working in the sun without enough water or white oxidized frames will almost always leave streaking of some sort. Try to only make 2 passes per window thats the key. Don't try and be fancy and try the "s" method stick with left to right or up to down. For screens work on the inside of the home first taking the screens out and tossing them down or taking them down from the inside. Then wash and replace as you clean the outside of the home. This is the fastest method for me. I average around $50 to $60 an hour cleaning this way. If you are a beginner you should still make atleast $25.00 an hour or so. Tracks are extra and should be noted on your estimate sheet. Some people will try to take advantage of you if you do not point that out. .................................................. ..Mark
