Can you use WD-40 to clean foggy headlights? Yes, WD-40 can temporarily clear foggy headlights by removing oxidation. However, for long-term results, consider using a dedicated headlight restoration kit. This article explores how to use WD-40 effectively and alternative methods for maintaining clear headlights.
How to Use WD-40 to Clean Foggy Headlights
To clean foggy headlights with WD-40, follow these steps for the best results:
- Clean the Surface: Start by washing the headlights with soap and water to remove dirt and grime. Dry thoroughly with a clean cloth.
- Apply WD-40: Spray a generous amount of WD-40 directly onto the headlight lens.
- Wipe the Headlight: Use a soft microfiber cloth to wipe the headlight in circular motions. This helps distribute the WD-40 evenly and removes oxidation.
- Buff for Shine: Continue buffing until the headlight appears clearer. Use a dry part of the cloth to remove excess WD-40.
Why Use WD-40 for Headlight Cleaning?
WD-40 is a versatile product that can cut through oxidation and grime, making it a popular quick fix for foggy headlights. Its water-displacing properties help in cleaning and protecting surfaces temporarily.
Alternatives to WD-40 for Headlight Restoration
While WD-40 provides a temporary solution, there are more effective long-term methods to restore and maintain clear headlights.
Headlight Restoration Kits
Headlight restoration kits are designed specifically for this purpose and often include sanding pads, polishing compounds, and UV sealants. These kits provide a more permanent solution by removing oxidation layers and protecting the lens from future damage.
Toothpaste as a DIY Solution
Toothpaste contains mild abrasives that can help polish the headlight lens:
- Apply Toothpaste: Rub a small amount of toothpaste on the headlight using a soft cloth.
- Buff and Rinse: Buff in circular motions, then rinse with water and dry.
Baking Soda and Vinegar
This natural cleaning method involves:
- Create a Paste: Mix baking soda with vinegar to form a paste.
- Apply and Scrub: Apply to the headlight and scrub with a cloth.
- Rinse and Dry: Rinse off the mixture and dry the headlight.
Benefits and Drawbacks of Using WD-40
| Feature | WD-40 | Restoration Kits | Toothpaste/Baking Soda |
|---|---|---|---|
| Price | Low | Moderate | Low |
| Ease of Use | Very easy | Requires effort | Easy |
| Longevity | Short-term | Long-term | Short-term |
| Effectiveness | Moderate | High | Moderate |
WD-40 is quick and easy but doesn’t offer the lasting protection that restoration kits do. Toothpaste and baking soda are cost-effective, but also temporary.

Regular maintenance can prevent headlights from becoming foggy:
- Regular Cleaning: Wash headlights weekly to prevent dirt buildup.
- UV Protection: Apply a UV sealant after cleaning to protect against sun damage.
- Parking Practices: Park in shaded areas to minimize UV exposure.
