Foggy headlights can significantly reduce visibility and safety while driving. Fortunately, cleaning them is a straightforward process that can restore their clarity and improve your night driving experience. Here’s a step-by-step guide on how to clean foggy headlights effectively.

Why Do Headlights Become Foggy?

Headlights often become foggy due to oxidation, which occurs when the polycarbonate lens is exposed to UV rays. Over time, this exposure causes a cloudy or yellowish film to form. Other factors like dirt, road debris, and moisture can also contribute to the problem.

How to Clean Foggy Headlights: Step-by-Step Guide

1. Gather Your Supplies

Before you begin, make sure you have the following materials:

• Microfiber cloths for wiping and polishing
• Soap and water for initial cleaning
• Masking tape to protect the car paint
• Sandpaper (1000, 2000, and 3000 grit) for sanding
• Headlight restoration kit or toothpaste as a DIY alternative
• UV sealant to protect against future oxidation

2. Clean the Headlights

Start by washing the headlights with soap and water. This removes surface dirt and grime, making it easier to assess the extent of oxidation.

1. Mix soap with water in a bucket.
2. Use a microfiber cloth to scrub the headlights.
3. Rinse with clean water and dry with another cloth.

3. Tape Around the Headlights

Use masking tape to cover the areas surrounding the headlights. This protects your car’s paint from accidental scratches during the sanding process.

4. Sand the Headlights

Sanding is crucial for removing the oxidized layer. Follow these steps:

1. Wet the 1000 grit sandpaper and gently sand the entire headlight in a horizontal motion.
2. Move to 2000 grit sandpaper and repeat the process.
3. Finish with 3000 grit sandpaper for a smooth finish.

Tip: Keep the sandpaper and headlights wet to avoid scratches.

5. Apply a Restoration Product

Once sanding is complete, apply a headlight restoration product or toothpaste:

• For a restoration kit, follow the manufacturer’s instructions.
• For toothpaste, apply a small amount to a clean cloth and rub in circular motions.

6. Polish and Seal the Headlights

After applying the restoration product, polish the headlights with a clean microfiber cloth. Finally, apply a UV sealant to protect against future oxidation.

Practical Example: Toothpaste Method

The toothpaste method is an effective DIY solution:

1. Apply toothpaste to a damp cloth.
2. Rub the toothpaste onto the headlight in circular motions for 5 minutes.
3. Rinse with water and dry.
4. Apply a UV sealant for long-lasting results.
