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.
I sounds like maybe you are leaving “lines” of water behind , not scratches. Next time you’re at one of these jobs take your finger nail and run it across the scratches.
Is this directly on glass? Or on tinted windows? Sometimes when I clean really dirty tinted windows, I have a bit of trouble with bad trail lines from the squeegee. If it is directly on the glass with no tint, some steel wool would most likely take it out, if it’s on tint, you’d might just need to do some extra washing with a good clean soapy water mix.
Just my thoughts from the comments I’ve read here.
