Step 1: Wash and Sand Horizontally

Clean the hazy headlight with warm soapy water.
Rinse thoroughly with clear water and let dry.
Then, mask the area surrounding the lens to avoid scratching the paint.
Soak the sheets of sandpaper in water, then begin with the grit that best suits your needs.
Sand moves in one direction.
Step 2: Rinse and Sand Vertically

Rinse and change direction with the next grit. Keep doing this until you’re finished with the 2,500-grit paper.
