clean yellow headlights with baking soda

Yes, you can clean yellow headlights with baking soda, and no, it’s not sorcery—just chemistry with better manners.

Wash the lens, mask the paint, then make a thick paste (about 3 parts baking soda to 1 part water) and rub with a damp microfibre in small circles for 2–3 minutes.

Rinse, repeat if needed, then wipe with isopropyl alcohol and seal with a UV protectant; otherwise the yellowing will return faster than a magpie in September.

If the lenses are badly oxidised, step up to wet-sanding (1500–2000 grit), plastic polish, and a proper UV clear coat, or just replace the units and save the drama.
