So the last couple sliding doors that I’ve cleaned have had a long smudge down the side of the door. I really cant figure out what it is, or what is causing it. When i practice on my own sliding doors , it doesn’t happen! Am i using too much soap ? Or not enough water ?
I’m at a loss right now for what is the culprit. It looks horrible though and i had to spend and extra 20 minutes today buffing out the doors with paper towel.
