01Tape and sand ladder
Wash lens. Tape paint, rubber, trim tight. Wet-sand 800 grit in even strokes until yellow layer dulls uniformly. Keep surface wet.
Move to 1000, then 2000 — each grit erases previous scratches. Rinse between grits.

Restore Foggy Car Headlights DIY
Sand, polish, UV seal — clear lenses in an afternoon without a new assembly
1h 30m3 photographed stepsBeginner
Auto life hack that improves night safety: tape around the lens, wet-sand 800→1000→2000 grit, polish with compound or toothpaste for light haze, wipe clean, apply UV clear sealant so yellowing doesn't return in months. Foggy headlights cut light output — this brings it back.
What you'll learn
- Tape paint and trim — sand only the lens
- Wet sand progressively finer — don't skip grits
- Polish until haze clears
- UV seal is mandatory or fog returns
