Are you tired of faded BMW headlights? Nothing is more embarrassing than driving a luxury vehicle with oxidized, cloudy, and hazy headlights.
What you will need
- Headlight Restoration Kit
- A headlight restoration kit will contain several sanding discs such as 500 grit, 800 grit, 3000 grid, rubbing compound, and applicator pads.
- Power drill
Your power drill needs to have a speed in the 1200-1600 rpm range. The drill can be cordless or corded. It doesn’t matter as long as it has the recommended rpm. Variable speed drills can be tricky as you can’t easily control the speed.
- Painter’s Masking Tape
Use masking tape to protect your car’s paint and trim. It is easy to remove and won’t damage your paint. Electrical tape is another alternative. It comes off easily, and the sanding discs can’t cut through it easily.

- Park the BMW on level ground, preferably outside.
- Use masking tape to cover the body panels around the headlight.
- Attach the pad holder to your drill, then attach the 500-grit sanding disk.
- Place the drill flat on the headlight lens and turn on the drill. You don’t need to apply much pressure on the headlight. Slowly move the drill over the BMW headlight to remove the haze. Go over the foggy BMW headlight covers/lens several times. At this point, the BMW may look even more hazy and foggy. Clean the BMW headlight with a cloth to remove the dust and inspect it periodically. Your BMW headlight lens should have an evenly white look. This step is very critical if you want your BMW headlight lens to look new in the end.
- Remove the 500 grit disk and install the 800 grit disc. Follow the same procedure as in the previous step to remove haze from your BMW headlight. Sand the headlight with 800 grit for at least five minutes.
- When you finish the 800 grit disc, reuse them, but apply water to the headlight. Use 800 grit disc and water to clean your BMW headlight for at least five minutes.
- Next, remove the 800 grit disc and install the 3000 or 1000 pads. Apply water to the disc and the headlight lens. Clean the headlight for at least five minutes. You should see a white milky residual. Repeat this step several times until you no longer see the white residual. During this procedure, make sure to spray water on the headlight constantly.
- Remove the previous disc and mount the foam pad on the drill. Apply a small amount of the rubbing compound to the foam pad. Without turning the drill on, rub the pad on the headlight several times, then turn the drill on.
- Polish your BMW lens with the rubbing compound. If you still notice any scratches, you may want to reapply the 3000 pads.
- Remove the tape and clean the area around the headlight.
- Enjoy your “new” and clean BMW headlight.

Notes
- Note that if your BMW bumper or fender were poorly painted, the tape might pull out the paint when it is removed. For this reason, we recommend that you use painter’s masking tape. Make sure to apply two strips of tape, or the sanding disks may cut through the tape and damage your BMW’s paint.

Not only do fading BMW headlights look ugly, but they also reduce the low-beam light output making it harder to see at night. You can even fail state safety inspections in some states.
Frequently Asked Questions
What is the best way to restore foggy BMW headlights?
The best way to restore those ugly BMW hazy headlights is to use sandpaper to remove the oxidized layers from the headlight lens. We start with 500-grit sandpaper. This step removes all the oxidation from the BMW headlight. Next, we use 800-grit sandpaper, which removes the scratches. After that, we use 1000 or 3000 grid discs to make the lens look nice and clean. Ultimately, we apply paste to make BMW headlights look new. This method works best and lasts for years compared to other methods where only paste is applied. Don’t waste time with methods such as using toothpaste or coke to restore the headlight; such methods won’t last. If you want to permanently restore your BMW headlights, use the method described here.
Will the BMW headlights turn foggy again?
Not for several years. Removing all of the oxidation from the headlight could take years to come back again.
How much does it cost to get your headlights clean?
It can cost around $20 to $200, depending if you cleaned it by yourself using a restoration kit or if it is done professionally.
