How Do You Remove Fine Hairline Scratches From Car Windshield?
Start by cleaning the windshield thoroughly, using Bon Ami scouring powder. This is talc, and will not scratch. Use clean, new paper towels for this. Then, get polishing compound intended for glass–inquire at an auto parts store. You can do this with an electric drill and angle head with a buffing wheel–it really isn’t done by hand, although it could be. It takes a lot of work that way. Remember, any tiny piece of grit you pick up will make another scratch. Or have a professional do it, as someone else suggested. But glass can be brought to a high polish by an amateur–a lot of people make their own telescope mirrors. That market is a source of grinding compounds if you can’t find them anywhere else.
