The windshield in my new "old" LeSabre has scratches, little cracks about 3/16" round, and the biggest thing is years of wiper insert rubber residue ground into the surface. I can live with the few scratches and cracks, they're small enough and not distracting, but that schmear of wiper rubber has got to go.
About ten years ago, I found a way to remove this stuff. I got it off the internet and didn't write it down. Now I can't remember it. There were two things - - 0000 steel wool, and either mineral spirits or denatured alcohol or.. or what?
Anyone know what I'm talking about?
This isn't oil or tar residue (road grime). I did give it a shot with what I already have in my cabinet - 0000 steel wool and some Comet cleanser.. no Bon Ami. This made the clean glass cleaner, and it shines like heck, but it didn't put a dent in the rubber residue. I've got some rubbing compound - I'm going to try that on a small, out of the way spot.
Sure, I could go out and get a small container of mineral spirits and denatured alcohol, but that would take all the fun out of this. I'm saving those for next to last solutions. My last solution will be a new windshield.
