Looking for advice on how to get rid of this vertical line at my windshield wiper end of travel. Only visible when rains, but more permanent than typical wiper streaks. Is annoying because it interferes with sight. Glass is maybe ten years old. I've read that it could be a silicone residue of Rain-X (I often used their wipers, which I replace basically annually). Goo Gone didn't work. Some ideas I've seen: vinegar, acetone, Magic Eraser, polishing compound, BarKeepers Friend, Rain-X Xtreme Clean, Glassparency Glass & Chrome Polish.

Sounds like you've done it all cleaning wise. I'm guessing new wipers didn't resolve the problem. I'm a big fan of OEM or Bosch.

 

try a clay bar or an light grit glass olishing compound..

 

i have not tried all those things, I was listing options I read about.

 

Do what Derf00 said.

 

That line is caused by the smaller wiper, which rhe larger wiper cannot remove. Found out that the new wipers have some tar/gunk substance causing it to stain the glass. I cleaned the wiper blade to remove the tar/gunk as best as I could using dishwasher soap, and I cleaned the glass to get rid of the tar residue, and now it works much better. You might have to do this a few times before all gunk is gone. Hope this helps...

 

Tooth paste works well too if you have a chamois cover for your car polisher.
