Apply a liberal amount of polishing compound to a handheld buffing pad. If you are removing a large area of scratches, you may wish to use an electric buffer for faster results.
Buff the scratched area using a rapid, circular motion and firm pressure. If you are using an electric buffer, move the pad gradually across the scratched area.
Check your progress by wiping the compound off the glass with a microfiber cloth. Reapply more compound to the pad or electric buffer as needed.
Wipe the area clean with your microfiber cloth once the scratches are no longer visible. Spray the tempered glass with glass cleaner and wipe dry with a paper towel.
