<strong class='bbc'>Steel wool those spots and the glass will water spot easier and deeper than before. You can not help but inflict very small marring in the glass by doing so.

I've been trying to remove some goop from the windshield of my '02 WRX to very little avail. I've used cleaner and newsprint, Bon Ami and scrubber, Prep Sol and finally Windex and 0000 steel wool. Far and away, the best results came from the Windex/steel wool combo. Unlike Ron's experience, I've noted no damage with what is a very soft glass (they just don't heat treat windshield glass like they did in the "old days")
