How to clean cloudy car headlights with toothpaste

Toothpaste has a mild abrasive that can polish away light haze on plastic headlight lenses. This suits anyone with dull, yellowed lights and a tube of plain white paste. You only need a few household items, and you should spot-test first.

What you need

Steps

  1. Wash the headlight with water and a cloth to remove dirt and grit. Dry it fully so you are not grinding dust into the plastic.

  2. Tape around the edges of the lens with masking tape. This keeps toothpaste off the paint and trim.

  3. Squeeze a pea-sized blob of plain white paste onto a soft cloth. Avoid gel and any paste with whitening beads.

  4. Rub the paste onto the lens in small circles with firm, even pressure. Work one section at a time for about a minute.

  5. Wipe the paste off with a clean damp cloth and check the lens. Repeat the rub and wipe if haze remains.

  6. Rinse the lens with clean water and dry it with a fresh towel. Remove the tape once the surface is dry.

Tips and common mistakes

Spot-test on a small corner first, since some pastes are too abrasive and can dull the plastic.

Use paste, not gel, because the gel lacks the fine abrasive that does the polishing.

Rinse off all residue, as dried toothpaste leaves a chalky white film.

Toothpaste only fixes light surface haze, so deep yellowing or cracks need a proper headlight kit.

Questions

Does toothpaste really clear headlights?

It can polish away light oxidation and grime because of its mild abrasive. It will not fix deep yellowing, scratches or cracks.

Which toothpaste should I use?

A plain white paste works best. Skip gels, whitening beads and anything with strong colours.

Will this damage my paint?

Toothpaste can dull paint and trim, so tape off the edges and rinse any spills right away.
