Just bought a new (to me) 04 F-150 and the driver side windshield has marks from the wiper. Is there a polishing compound I can use to remove this? The marks aren't deep, just like a little cloudy from rubbing?

 

Rubbing alcohol should work. You can use that to clean the blades too.

 

If a good cleaning doesn't work there are many polishing kits available. Google "glass polishing kit".

 

Yes they make a glass polishing kit.

attach it to a orbital sander and set the RPM to no more than 4k.

Diamondite® Glasswork System Kit restores, polishes, and protects auto glass windshields and windows. Diamondite glass polish and glass sealant.

But as a note though: If the gouges are too deep the polisher will not remove the scratches. This formula was made to remove fine swirls or scratches.

if you have real bad water spots, a helpful hint to remove those are a water bottle with water and some vinegar.

I have used the above kit. It does do good work, but dont expect miracles.

 

add glass coverage, wait a week, then throw a rock at it
