Hey, so lately on a couple of contracts I seem to leave a bunch of scratches. Nothing horrible, but some of the lines are matching my fanning method. They appear on 2013 commercial windows.
I seem to create scratches on the inside and outside panes of that job and when I’m using both Pulex and Ettore rubber.
Also I’ve cleaned my washer and tried 2 different brands.
I’ve done these windows for years without any issue. The scratches seem to appear out of nowhere on pretty clean panes.
What am I doing wrong?
