It’s a small detail that can really make all the difference. Over the years, polycarbonate headlights deteriorate due to UV rays, pollution, and harsh weather. As a result, they become opaque, yellowed, and lose their effectiveness at night. In addition to being a safety hazard, this gives the car a worn and unflattering look…
An amazing homemade paste… made from an old battery!
Yes, you read that right. Some used batteries contain a mixture of carbon and manganese oxide which, combined with other simple ingredients, can restore brightness to your headlights.

Powdered charcoal (from zinc-carbon batteries)
White toothpaste, preferably with baking soda
White vinegar, our ultimate cleaning ally
Together, they form a slightly abrasive paste capable of removing dull residue and micro-scratches.
