When driving at night or in adverse weather conditions, having clear and bright headlights is crucial for safety.

While there are various methods to clean headlights, using WD-40 is an effective and affordable solution.

1. Gather the Necessary Materials

Before starting the cleaning process, gather all the required materials. You will need:

2. Choose the Right Location

Select a well-ventilated and shaded area to work on your car’s headlights. Avoid direct sunlight, as it may cause the WD-40 to dry too quickly.

3. Clean the Headlight Surface

To begin, wash the headlight surface with car wash soap and water to remove any loose dirt or debris. Use a soft cloth or sponge to gently scrub the headlights, ensuring all dirt is removed.

4. Apply Masking Tape

To protect the paint around the headlights, apply masking tape to the edges of the headlights, leaving only the lens exposed.

5. Apply WD-40 to the Headlights

Shake the WD-40 can well and spray a generous amount onto the headlight lens. Make sure the entire surface is covered with WD-40.

6. Buff the Headlights

Using a clean microfiber towel, start buffing the WD-40 onto the headlight lens in a circular motion. Continue this process until the lens starts to clear up and the haze begins to disappear.

7. Wipe Off Excess WD-40

After buffing, use another clean microfiber towel to wipe off any excess WD-40 from the headlight surface. Make sure to remove all the residue for a clear finish.

8. Repeat if Necessary

For severely hazy headlights, you might need to repeat the process a few times until the desired clarity is achieved.

9. Clean the Other Headlight

Follow the same steps to clean the other headlight of your vehicle.

10. Rinse the Headlights

Once both headlights are cleaned and free from WD-40 residue, rinse them thoroughly with water to remove any remaining product.

11. Dry and Inspect the Headlights

Use a dry microfiber towel to dry the headlights completely. Inspect the headlights to ensure they are clean and clear.

12. Apply a Protective Sealant

To prolong the clarity of your headlights, consider applying a UV-resistant protective sealant. This will shield the headlights from future damage and keep them looking new for longer.

Having clean and clear headlights is not just about aesthetics; it is crucial for safe driving. Clear headlights improve visibility, allowing you to see and be seen on the road, especially during low-light conditions.
