Started window cleaning two weeks and now bought brushes and squeegee from Home Depot did a couple businesses realize after the first week some of the windows look scratched, and I could tell it was from me from the pattern. I tried my buying and using professional equipment didn't work, i wash and brush out each mirco fiber brush after each job very well and still get scratches I try pre-treating the window with the water and a duster didn't work sometimes I'm still getting scratches. Is there anything l'm doing wrong? Can you guys please help? Thank you.
