I just tried to clean all the windows in my flat. In general, they now look great; should have done it ages ago!
However, maybe half of the windows have very faint streak marks on them. The sort of lines that you might get from running very-slightly-greasy fingers across the glass. It's only visible if the light hits it right, and/or if you look very closely, but it is there. It's not lint, just "lines" in the polish, I think.
I've tried to "buff" it out with further rubbing with a dry, clean sheet of paper towel (which is what I used to do the original cleaning), but no joy.
My instinct is that I used too much window cleaner (the windows were VERY dirty prior to cleaning) and these streaks are excess cleaner/polish?
Is my guess correct? Is that a thing that happens if you use too much cleaner?
Either way, is there an easy way to fix this?
