Cleaning car headlights from yellow fog is essential for maintaining visibility and safety on the road. Yellowing occurs due to oxidation and exposure to UV rays, but with the right tools and techniques, you can restore your headlights to their original clarity. This guide will walk you through the process step-by-step, ensuring your headlights shine bright once again.

Why Do Car Headlights Turn Yellow?

Car headlights turn yellow primarily due to oxidation. The plastic lenses, typically made from polycarbonate, are exposed to sunlight, road debris, and harsh weather conditions, causing them to degrade over time. This degradation results in a cloudy, yellow appearance that can significantly reduce the effectiveness of your headlights.

What You Need to Clean Car Headlights

Before you begin, gather the following materials:

• Microfiber cloths
• Masking tape (to protect the car’s paint)
• Sandpaper (1000, 2000, and 3000 grit)
• Plastic polish or headlight restoration kit
• Spray bottle with water
• UV sealant (optional for long-lasting protection)

Step-by-Step Guide to Cleaning Headlights

Step 1: Prepare the Area

1. Wash the Headlights: Clean the surface with soap and water to remove dirt and grime.
2. Dry Thoroughly: Use a microfiber cloth to ensure the headlights are completely dry.
3. Tape Off Surrounding Areas: Use masking tape to protect the paint around the headlights.

Step 2: Sand the Headlights

1. Wet Sanding: Begin with 1000 grit sandpaper. Spray water on the headlight and sand in a circular motion.
2. Progressive Sanding: Move to 2000 grit, then 3000 grit, ensuring you keep the surface wet.
3. Wipe Clean: After sanding, wipe the headlight with a clean cloth.

Step 3: Polish the Headlights

1. Apply Plastic Polish: Use a clean microfiber cloth to apply plastic polish or a headlight restoration compound.
2. Buff the Surface: Work the polish in with a circular motion until the headlight is clear.

Step 4: Seal the Headlights

1. Apply UV Sealant: To prevent future yellowing, apply a UV sealant following the product instructions.
2. Allow to Cure: Let the sealant dry completely before using the vehicle.
