How to Polish the Front Windshield

A clear view through the front windshield of any vehicle is a necessity for safe driving. Still, any number of things commonly cause scratches and abrasions in the front windshield that inhibit the driver's view. These slight but consequential marks aren't removed with merely washing the windshield. Instead of replacing a costly windshield, some car owners use a polish designed specifically for clearing these marks away. This is not meant for repairing cracks, but for issues such as when the metal of a windshield wiper has scraped a mark.

Instructions

1

Clean the windshield thoroughly, inside and out. Allow it to dry completely.

2

Place masking tape on both sides of the scratch the width of the polishing bob on the inside of the windshield. This is your polishing guide.

3

Place protective covering over any of the vehicle's painted and non-glass surfaces that could potentially come into contact with polish. Secure the covering to the vehicle.

4

Soak the felt of the polishing bob in warm water for about a minute. Mix the polishing compound according to its directions. Cover the area to be polished with warm water.

5

Apply polishing compound to the glass. Stay within the lines of the masking tape.

6

Attach the polishing bob to the drill. Polish the area at a speed of about 400 to 600 rpm using the flat end of the polishing bob. Apply even pressure, use a back-and-forth motion and stay within the taped lines.

7

Use a sponge and water to remove any remaining polish. Clean the windshield with glass cleaner. Repeat polishing if necessary.
