How to Clean Fogged Headlights: DIY Tips to Make Your Headlights Cleaner and Brighter

Driving at night or in low visibility conditions can be a challenge, and bright headlights are essential for safety. Many people know to check for blown headlight bulbs, but the clarity of the headlight lenses is just as important. Over time, headlights can fog up due to the elements, reducing their effectiveness. Let’s take a look at what causes headlights to fog up and how you can effectively clean them using DIY methods.

What causes headlights to fog up?

If your headlights appear dim or have a yellowish tint, it’s likely because the lenses are fogged up. This problem is common in modern headlights made from polycarbonate instead of glass. While polycarbonate lenses are more scratch-resistant and durable, they do degrade over time when exposed to sunlight, causing their outer layer to break down and absorb blue light. As a result, the light they emit is dim and has a yellowish tint. Fortunately, you can restore their clarity by using a few simple techniques.

The Best Ways to Clean Foggy Headlights

Headlight cleaning products are readily available at automotive stores. Look for products labeled "headlight restoration kit" or "headlight lens cleaner." These products make it easy and effective to clear up foggy headlights.

If you need to clean your headlights with household products, toothpaste and baking soda can also be effective. Both products contain mild abrasives that can remove the fog layer without scratching the lenses. Other products, such as Rain-X, can help polish your headlights and restore their clarity. It’s always a good idea to have a cleaning kit on hand.

Steps to DIY Headlight Restoration

Here is a simple step-by-step guide on how to clean headlights at home:

Gather the necessary materials
To get started you will need:

• Headlight restoration kit, toothpaste or baking soda
• Cloths or towels
• Latex gloves (for sensitive skin)
• Water
• Soft brush
• Gentle cleanser

Remove dirt from surfaces
First, spray the headlights with a mild cleaner. Gently wipe any dirt, insects, or other contaminants from the surface.

Dry the surface
Use a clean towel to make sure the surface is completely dry before applying cleaner.

Apply cleaner to the headlights
Apply an appropriate amount of cleaning agent to the lenses – toothpaste, baking soda paste or a product from a headlight restoration kit can be used. Leave the agent for a few minutes to set slightly.

Scrub your headlight lenses
Using a soft brush and circular motions, gently scrub the lenses. You should notice the yellowing and haziness begin to disappear as you clean the surface.

Remove excess cleaning agent
Clean off any residue with a towel. If any residue is stubborn, rinse with clean water and pat dry.

Tips to prevent your headlights from fogging up

To keep your headlights in good condition, consider applying UV protection after cleaning. Regularly wiping the lenses with a gentle cleaner can also prevent them from fogging up again.

Summary
With the right products and a little DIY effort, you can restore the clarity of your headlights, improving the look of your vehicle and the brightness of your lighting. Follow these simple headlight restoration steps to keep your lenses clean and your visibility on the road clear.
