How To Clean Your Headlights With Toothpaste

How To Clean Your Headlights With Toothpaste

If you touch your headlights on the outside and they are not smooth, all pitted, that indicates that they should be polished out. So you want to make sure you use a toothpaste that has some grittiness to it and is an actual paste and not a gel. I usually use a toothpaste that has a baking soda and peroxide which will help get your headlight lenses clear. If your toothpaste isn’t gritty, then you can add some baking soda to the toothpaste to clean foggy the headlights.

  1. Start off by getting a bunch of toothpaste and rub it in. Make sure you rub it in good cover.
  2. Use a toothbrush and brush it in there really good! The more yellow the headlight is, the longer you will have to brush and you might even have to do two applications of toothpaste.
  3. Another tool you can use is a Dremel with a buffing wheel on it. (Check the price on amazon) Just buff all of the toothpaste into the headlight instead of brushing it in only with a toothbrush. This might give you better results. Make sure you use the low-speed setting (15k rpms or less). You don’t want this to spin fast because you will melt your plastic.
  4. Wash it off with some water and wipe it with a clean paper towel.
  5. Apply wax on your headlights.
  6. Wait 5 minutes and remove the wax with a cleanOpens in a new tab.

How To Clean Your Headlights With Sandpaper

How To Clean Your Headlights With Sandpaper

If you can’t clean your foggy headlights using this method, then you need new headlights. For this method, you will need three different grits of sandpaper – 400 to start, then 600, then 2,000. The lower the number, the more abrasive the sandpaper. You will also need some warm water. Make sure your headlight is clean before you start.

  1. Get the headlight soaking wet.
  2. Tape off your paint. You are going to use a sandpaper and you don’t want to damage your paint. If your headlights have rubber trim around them, then you are good to go.
  3. Get your sandpaper (400)and soak it wet.
  4. Start by normal motions. Keep a flat surface, do not try to dig in.
  5. Inspect. What you want to see is a uniform haze. It’s not going to look clear at all, and that’s good. Touch the surface. It should feel kind of smooth. There might be a little bit of grittiness which is fine. If there is a lot of grittiness you want to sand that spot pretty good.
  6. Move to the next grit 600 and again soak your sandpaper wet.
  7. After you get this grit done, wipe it off again to see what you have to work with.
  8. Next grit is 2000 mm. If you have 1000, you could do 1000, then you could do 2000. It’s up to you.
  9. Get your headlight soaking wet and get your sandpaper soaking wet. With the 2000 grit, you might have to apply a little bit more pressure.
  10. Wipe your headlights with a towel.
  11. If you are not satisfied with the results, you can also use the toothpaste trick.

How To Clean Your Headlights(Permanently) With UV Coating

How To Clean Your Headlights(Permanently) With UV Coating

This is a great way to clean and restore your foggy headlights permanently. This will cost you around $10 per headlight. The other methods with home remedies such as vinegar, baking soda, toothpaste, or the 3m kit work great, but they are not permanent. Your lights will eventually become hazy and oxidized. I’m about to show you the only permanent method that doesn’t require any maintenance such as adding wax or adding a sealer every so often. Not only do hazy oxidized headlights look bad, they also decrease the value in your car. So not only will you make your car look better, but you’re actually going to help increase the value of the car by fixing your headlights.

How To Super Clean Your Windshield

Everything you need to do the job:

  • Scissors
  • Garbage Bag
  • Tape
  • Paper Towels
  • Sandpaper 400grit, 600grit, 2000grit
  • Spray bottle with water
  • Alcohol
  • Gloss Clear for plastic

The big thing is you want them to be non-yellowing and UV resistant. The reason why your headlights are all foggy, yellowing and oxidized is because of the clear coat on the headlights gets chipped off over time from rocks hitting it from just. This method is going to put a nice barrier so that the plastic can’t get yellow and hazy again. Most people have scissors and a garbage bag and some paper towels, but if you’re going to buy the other stuff it’ll cost you around $20. So you figure, to make your headlights permanently clear $10 a headlight. That’s not bad, especially since some headlights can cost over a $100. I’ve seen headlights that are $250 each. I’ll show you the whole process. It’s quick and easy.

UV Coating Product

Get Started

  1. If your headlights are easily removable I would remove them. It’s a lot easier to do this off the car. If not, you can do this process without removing your headlights.
  2. Tape around the headlight(if you are not going to remove it). Make a nice barrier around the edge. I usually use extra wide painters tape.
  3. Put the garbage bag around the light to fully cover the pain on the vehicle.
  4. Start with 400 grit sandpaper. If your headlights aren’t that bad, you could start with 600 grit sandpaper which is a little bit finer. Then we’ll finish it off with a little bit of 2,000 grit which is super fine.
  5. Spray the headlight with water. Make sure both surfaces are nice and wet. The water acts as a lubricant and prevents deep scratches into the surface.
  6. Start with circular motions. Do not apply a lot of pressure. You’ll notice like a milky color running down. That’s all that oxidized yellowing plastic that’s coming off your headlight.
  7. Move to the 600 grit. Again get your headlight nice and soaking wet, get your sandpaper nice and soaking wet. Do a bunch of swirling motion with the 600 grit, then start with horizontal sanding. With this type of sanding, you will have that top layer of the oxidize headlightOpens in a new tab.
  8. Clean the headlight with water before starting the next step.
  9. Move up to the 2,000 grit. You don’t want to press really hard on this, you just want to skim the surface. You’re just going to cut down some of the edges that the 600 grit put on here. After you do enough of the swirling motion, you could do the horizontal motion. This is going to be the final touch. Don’t worry if your headlights are still hazy.
  10. Dry it with a paper towel.
  11. Get your alcohol and put it on a low lint paper towel. Clean the headlight lens off. The alcohol removes any oils from your hands that may have gotten onto the lens, and it also makes the lens dry quickly. You can apply alcohol multiple times.
  12. As your alcohol is drying, cut your garbage bag open.
  13. Start your clear coat application. Make sure you follow the instructions on your clear coat. You don’t want thick coats. Thick coats are going to run. Make sure you do light coats, even sprays.
  14. Let it sit for five minutes and then add another coat. Add 3-4 layers with a 5-minute rest in between. Make sure when you’re spraying you’re also getting the top edge of the light and the corners of the light. Depending on how your light is shaped, you want to make sure that you touch all the spots on the light.

That’s it. The UV Coat does not only make your headlights look good, but it’s going to protect the headlightOpens in a new tab.

You can also add some wax, but it’s optional.

BONUS: How To Fix Headlight With Moisture In It

You might have noticed that some headlights have water drops in them. This is actually an issue. There shouldn’t be water inside the headlights. If the water gets into contact with your light, it will burn it. This is an easy fix and you don’t need to be a mechanic to perform this task. Follow my step by step guide:

  1. Start off by removing your headlight. All headlights have 2 or 3 bolts that you need to unscrew. Usually, there is one on the left and one on the right side as well as one on the bottom of the headlight. After you remove the bolts, you will have to disconnect the cable.
  2. After you removed the headlight and the cable connected to it, take your light bulb out.
  3. Fil your headlight with water all the way to the top.
  4. See where the leakage is.
  5. After you located your where your leakage is, take the water out and dry your headlight.
  6. After you dry your headlight, clean the surface where the water is leaking from. You can use a glass cleaner or just soapy water.
  7. If the surface is rough, you can sand it a little bit.
  8. Apply silicon on the surface and spread it with your fingers. Leave it to dry.
  9. You can test to see if you sealed the leak by filling the headlight with water.
  10. Re-install your headlight.
