How to clean your car headlights

part1 ready to start

1.Check your headlights to find the most reasonable solution. Headlights are hazy and not as clear as they used to be? You might as well check it with the headlights on and off during the day. Only by understanding the extent of the damage can you determine which method is most effective. See if you need to have it checked by a professional mechanic or just replace the headlight. Extensive wear and scratches mean the problem is serious.

2.Wash your headlights with regular car cleaner. Grit and grease from the road make your headlights dirty and hazy, making it impossible to accurately judge the extent of the damage. Start by washing your car with warm water and car wash, wipe down your headlights, and let them dry completely. Then check the clean headlights to find the problem.

3.Look for sgns of fogging. When the entire headlight hard coating wears away, exposing the soft polycarbonate lens, the lens will begin to become scratched and become hazy. The lens surface quickly becomes old, rough and dull.

• If that's the problem, a quick cleaning of your headlights with some inexpensive products can go a long way in slowing down degradation. However, you may also need to do a full cleaning.

4.Look for signs of yellowing. When the dura mater begins to thin and separate from the polycarbonate lens, it will cause the headlights to turn yellow. The ultraviolet wavelength spectrum creates new repeating segments in the carbon chain, which absorb blue light and cause the headlights to turn yellow.

• When you notice yellowing on your headlights, use Rain-X or some polish to clean them more thoroughly and repair the damage.

5.Look for signs of peeling and cracking. As the dura mater begins to degrade, you may notice stains in places, such as on the top half of your headlights or in the corners. The dura mater looks like it's about to fall off. Finally, the cracks penetrate deep into the lens and can only be left to professional technicians to repair the surface.

• If so, you may need to replace the headlights, or have them repaired (which may be more expensive). In the meantime, try to give them a quick cleaning and research how much it will cost to buy new headlights.

6.Have your glass headlights inspected by a professional mechanic. Most headlights are made of plastic and can suffer from the problems mentioned above. The headlights of antique cars and older cars are made of glass, which is more complicated and is best left to a professional mechanic for inspection. If the glass headlights are worn, it's a good idea to call a mechanic to check them out.

part2 Sanding headlights with sandpaper

1.Prepare several grades of wet and dry sandpaper. First, you'll have to use several sheets of wet and dry sandpaper, ranging from coarse to fine, to remove the headlight scratches. 3M is the best brand. Buy at least a coarse sandpaper (around 1500 grit) and a finer one (around 2000 grit) to sand the worn areas of the headlights. If you want, you can also sand with a coarser sandpaper first.

2.Apply tape around the headlights. Every time you sand your car, be careful not to use too much sandpaper to avoid accidentally scratching the paint. It is best to use some painting tape to stick to the edge of the headlight (where the light meets other painted parts) to prevent the paint from being scratched off. This is not a mandatory step, but it’s good to be prepared.

• Before you start sanding, it's a good idea to wipe down your headlights again with a clean paper towel and a small amount of rubbing alcohol. They dry quickly and you can start sanding.

3.Wet the sandpaper and start sanding. Use a spray bottle or small bucket filled with water to wet the coarse sandpaper and sand the headlights thoroughly. Using even pressure, buff away the headlight scratch until it becomes dull and flat.

• If the original coating starts to peel off, you'll notice that the headlights have hazy "lines" and change shape after you sand them. It's best to use sandpaper to completely remove the coating.

4.Change to finer sandpaper. After sanding once with coarse sandpaper, switch to finer sandpaper and repeat the above process until the headlight changes from dull to smooth.

• If the internal structure of the headlight makes it impossible to see the bulb from the outside, just sand it with 1500 grit sandpaper. The headlights are still hazy but flat and not yellowish.

part3 Polish the headlights

1.Choose a polish. After sanding the headlights and removing the hazy parts, it's time to apply polish. Aluminum polish is the best option to restore your headlights to their best condition. Non-abrasive acrylic tub and sink cleaner, specifically designed to clean plastic, is also effective .

• Want to save money? Many people use regular blue toothpaste instead of polish. Use only pure blue toothpaste and make sure it contains no hydrogen peroxide, whitening agents or other additives.

2.Pour the polish onto a clean microfiber cloth. Prepare a clean towel, pour out a small amount of polish (about the size of a coin), and focus on wiping a certain part of the headlights. For example, start by wiping an area of ??10x10 cm. Rub this small area repeatedly and evenly in a circular motion, and it will look brighter in less than 5 minutes. After wiping, continue wiping the next area.

• If you are polishing with a hand drill, pour the polish directly onto the sponge pad of the hand drill and wipe the headlights at a low speed. Wipe gently and slowly increase the speed while moving the sponge pad to wipe the headlights evenly. Take your time and only wipe 2.5 centimeters per second. This is faster than polishing by hand.

3.Continue wiping until the headlights become brighter. You need to put a lot of effort into it, as sometimes it may take up to three coats of polish to get the headlights to look the way you want. Continue polishing until you achieve the clarity and light sharpness you are happy with. Turn on your headlights and shine them on a garage wall or flat surface to test the polish.

4.Consider applying plastic tackifier. To protect your headlights and keep them in good condition, consider visiting your local body shop and having a mechanic spray the headlights with a plastic tackifier . Plastic tackifiers, combined with a few layers of automotive clearcoat, can greatly extend the life of your headlights and are inexpensive . Another cheaper option is acrylic floor wax. Apply a layer of wax and let it dry. You can apply multiple coats to make it more durable and reapply if necessary.
