  • Plastic or vinyl gloves
  • Soap and water
  • Spray bottle
  • Toothpaste
  • Automotive wax (optional)

Important considerations before cleaning dirty headlights

Safety First: Always work in a well-ventilated area and wear gloves to protect your skin.

Weather Conditions: Choose a dry, mild day to work on your headlights. Extreme temperatures can affect the curing of clear coats.

Test First: If using a new product or method, test on a small, inconspicuous area first. You may want to enlist the help of a professional car detailing service to clean your vehicle first.

Patience is Key: Rush jobs often lead to subpar results. Take your time, especially when sanding.

Regular Maintenance: Once restored, regularly clean your headlights and apply a UV-resistant wax to prolong clarity.

Legal Considerations: Be aware that in some regions, heavily tinted or modified headlights may not be legal. Always ensure your restoration complies with local regulations.

Environmental Impact: When cleaning, be mindful of where your runoff goes. Use environmentally friendly products when possible, and dispose of any chemical waste properly.
