Steps
Park in shade and let the headlights cool. Wash the lens with water and mild soap, then dry it fully so grit does not scratch the plastic.
Run masking tape around the edges of the headlight to protect the paint and trim from polish and sanding marks.
Squeeze a generous blob of plain white toothpaste onto a microfibre cloth or damp sponge and spread it over the whole lens.
Rub in small circles with firm, even pressure for 3 to 5 minutes, keeping the surface damp. Add water if the paste dries out.
Wipe the paste off with a clean damp cloth and check the lens. Repeat the toothpaste rub two or three times for heavy yellowing.
For stubborn cloudiness, wet sand the lens with 800 grit, then 1500, then 2000 grit paper, keeping it wet and rinsing between grades.
Polish the sanded lens with car polish on a soft pad until the haze clears and the plastic looks glossy again.
Seal the finished lens with a UV clear coat or headlight sealant so it does not yellow again within months.
Tips and common mistakes
Use plain white toothpaste, not gel or whitening types with coloured beads, which can leave streaks.
Keep the lens wet while sanding, or the paper will clog and scratch the plastic.
Do not polish in direct sun, because the paste dries too fast and works unevenly.
Skip the sealant and the headlights will cloud over again in a few months.
Questions
Does toothpaste really clear headlights?
It works as a mild abrasive that removes a thin layer of oxidised plastic. It helps with light yellowing, but heavy clouding needs wet sanding and polish.
How long does the result last?
Bare polished plastic re-oxidises in weeks to months. A UV clear coat or sealant makes the clarity last much longer.
Can I use an electric drill or polisher?
Yes, a foam polishing pad on low speed saves effort. Keep it moving and keep the surface wet so you do not burn the plastic.
