How long does headlight restoration last?

With proper UV sealant, 1-2 years. Without sealant, yellowing returns within weeks.

Is headlight restoration worth it?

Absolutely. A $15 DIY restoration avoids $200+ lens replacement and significantly improves safety.

It provides a temporary shine but doesn't actually restore the lens and wears off quickly.

Keeping your car headlights clean protects your investment and improves both appearance and performance. Here's the right way.

1
Tape around the headlights
Apply masking tape around the headlight to protect surrounding paint from abrasion.
2
Apply toothpaste
Apply whitening toothpaste generously to the lens. The mild abrasive polishes the oxidized layer.
3
Scrub in circles
Scrub with a microfiber cloth in firm circular motions for 3-5 minutes per headlight.
4
Rinse and seal
Rinse with water, dry, and apply UV sealant spray to prevent re-yellowing.

Yes. The mild abrasive polishes away oxidation. Whitening toothpaste with baking soda works best.
