- 2). Wait for the amount of time indicated on the compound's packaging. This is usually between five and 10 minutes.
- 3). Wash the compound off using warm water. Ensure all of the compound has been removed, checking around the frames and sides of the lens, too.

- 5). Rinse the glasses to remove any remaining metal polish.
- 6). Place a small amount of car wax onto the lens and apply pressure to manipulate the wax into the scratches.
