I used scotchbrite on some bird dropping on my windshield and now the scratches will not come out. I have used a Mothers polish applicator on a drill, Several brands of scratch remover (for paint),paint polishes, 600 grit emery paper and steel wool-0000 grade....no change. It is only a spot two...
I noticed my windsheild looks like it's been parked under a Maple tree when it gets moist. It was like this when I bought it so I don't know the source of this contamination. I have tried 0000-steel wool but it did not come off. Tar & Bug Remover don't work either. All suggestions welcome. Thanks.
