Steps
Wash the headlight lens with water and a cloth to remove dirt and grit. Dry it fully so you can see the real condition of the plastic.
Check the lens first. If it is cracked, has moisture inside or a damaged reflector, stop. This method only fixes outside oxidation.
Tape around the edges of the headlight with masking tape so the polish does not scuff the paint or trim.
Mix toothpaste with a small amount of baking soda and a few drops of water into a thick paste.
Rub the paste onto the lens with a cloth in small circles. Use firm, even pressure and keep the surface slightly damp.
Wipe the paste off with a clean damp cloth and check the clarity. Repeat the polish if haze remains.
For heavy yellowing, wet sand the lens with fine grit paper, keeping it wet, then polish again with the paste.
Dry the lens completely, then apply a UV sealant or plastic clear coat in a thin, even layer. Let it cure as the product label says.
Tips and common mistakes
Use plain white toothpaste, not gel, since the mild abrasive is what does the polishing.
Do not skip the UV sealant. Without it the yellow haze can come back quickly.
Keep the lens wet while sanding to avoid scratching the plastic.
Work in shade so the paste and sealant do not dry too fast.
Questions
Will toothpaste really clear yellow headlights?
It can remove light surface oxidation because the paste is mildly abrasive. Heavy yellowing usually needs wet sanding first, then polishing.
How long does the result last?
That depends on the UV protection you apply and your local sun exposure. A proper sealant or clear coat helps it last much longer than polishing alone.
Can I use this on cracked or wet headlights?
No. Cracks, moisture inside the lens, damaged reflectors and bad bulbs need repair or replacement, not polishing.
