Scrub with a baking soda and vinegar paste

Make a thick paste from baking soda and white vinegar, then scrub it onto cloudy headlights. The mild abrasive action of baking soda combined with vinegar's acidity helps dissolve surface grime and lightly polish the lens.

Steps

1. Clean the headlight lens and dry it.
2. Mix 2-3 tbsp baking soda with enough white vinegar to form a thick paste.
3. Apply the paste to the lens and scrub firmly with a cloth for 3-5 minutes.
4. Rinse thoroughly with water and dry.
5. Repeat if needed, then apply a UV sealant to protect the surface.

Why It Works

Baking soda is a gentle abrasive that buffs away the outer oxidized layer without scratching the polycarbonate. The vinegar helps break down road grime and mineral deposits.

Tips

• Best suited for light cloudiness — won't restore heavily yellowed or pitted lenses
• Lemon juice works as a substitute for vinegar
• Multiple applications may be needed for noticeable improvement
