Removing aluminum "skid marks" from glass.

Does anybody out there know what I could use to remove the silver streaks from the glass fronts of solar panels? Sometimes when unpacking panels and the frame of the one being moved rakes across the one under it, it will leave aluminum streaks on the glass. These seem to be fused onto the glass. Nothing I have tried will remove this stuff. Goof off, Mr. eraser, Windex, water, and lots of elbow grease, nothing removes it. I was hoping somebody knows of a way to get this stuff off.

    bon-ami cleanser.   Might take off the AR coating too.   Mercury will remove aluminum too, but it's hard to limit it.

    Just guessing... those skid marks are bare glass... there's nothing to remove.  Maybe they are where some anti reflective coating has been scraped of the glass.

    It will wear off over time or it has for me before. The sun is great for this :) even the stuff you do not want to come off :) :)
