The durability, versatility and cost efficiency of plastic make it a prevalent material in many industries. Since plastic is lightweight and corrosion resistant, many vehicle components are fabricated from it. Vehicle headlights are composed of molded polycarbonate plastic for resistance against cracks and chips. However, they become hazy and dirty over time from sunlight exposure and atmospheric chemicals. Keeping plastic headlights clean and polished gives them aesthetic appeal and provides drivers with proper visibility. Frequently clean and polish plastic headlights to add shine and ensure their longevity.

Clean and polish plastic headlights for appearance and safety purposes.

Step 1

Apply blue low-tack masking tape around the edges of the headlight to prevent damaging the nearby paint finish. Focus on one headlight at a time.

Step 2

Mix 1 tbsp. of dish soap with 1 gallon of water in a plastic container. Dampen a nonabrasive sponge in the soapy solution. Wipe the sponge gently over the entire headlight to remove loose abrasive dirt.

Step 3

Rinse the headlight with water to remove soap and loose grime. Dry the headlight thoroughly with a terry cloth towel.

Step 4

Apply a generous amount of polishing compound directly to the headlight. Rub a microfiber cloth over the headlight in circular motions to remove haziness and add shine. Buff the headlight with the cloth for 10 minutes.

Step 5

Inspect the headlight for remaining haziness or dullness. If more polishing is needed, smear more polishing compound over the headlight and continue buffing until you are satisfied with the results.

Step 6

Remove the masking tape from the nearby paint. Repeat the entire process on each remaining headlight.
