Headlight cleaning and care is an important part of ensuring driving safety, especially when driving at night or in dim light, rain and dust will affect the illumination of the headlights, which in turn affects the driver’s vision. Through regular cleaning and maintenance, the headlights can be kept in good working condition and improve driving safety.

 

So, how to clean the headlights?

First, you need to start the vehicle ignition switch and turn on the headlights. Please note that the headlight cleaning function can only be used when the headlights are on.

Next, find the windshield wiper spray lever on the right side of the steering wheel, hold the lever with your hand and bend it forward, that is, sit in the direction of the cab face, bend it and don’t let it go. In this way, the water spray pump on the bumper will extend out and spray the glass water on the headlights.

 

The specific steps for cleaning and caring for headlights are as follows:

1. Wipe the headlights with a rag.

2. Cover the edge area of ​​the headlights and the area that does not need to be repaired with tape.

3. Soak the 1000-grit sandpaper in cold water for 10 minutes, and evenly polish the headlight housing by grinding it back and forth in one direction.

4. Repeat the above work with 1500-grit sandpaper in different directions, and then repeat it several times with 2000, 2500, and 3000-grit sandpaper.

5. Apply the polish in a circular motion for about ten minutes.

Headlight cleaning devices are mainly used on vehicles using xenon lamps. This is because the advantages of xenon lamps are power saving, high brightness, high color temperature comfort, and long life. However, xenon lamps also have disadvantages, that is, the color temperature is higher, and the penetration is not as good as halogen lamps in rain, fog, snow and other weather. If there is dust and dirt on the headlights, the penetration will be worse, and it will also absorb part of the light source. At the same time, dust particles will make the light source become scattered, so the headlight cleaning device becomes very important.

Nowadays, headlight cleaning devices are basically high-pressure spray washing. The cleaning effect mainly depends on the distance between the nozzle and the light distribution mirror, the size of the water droplets, the contact angle, the speed of the water spray and the amount of water sprayed.

Car Headlight Cleaning and Care Tips-Headlight Restoration Kits

The following are the daily headlight cleaning and care methods provided by Wowiper:

 

1. Clean the lampshade regularly

 

Daily wiping

It is recommended to wipe the outer surface of the lampshade with a soft cloth every month to keep it clean.

When wiping the surface of the headlight, Wowiper recommends wiping the surface of the headlight with a soft damp cloth regularly to remove dust, stains and insect corpses. If the stains are stubborn, a small amount of mild detergent can be used, but the detergent should be prevented from flowing into the headlight.

When cleaning the gaps in the headlights, we recommend using tools such as soft brushes or toothpicks to clean the debris at the edges and gaps of the headlights to prevent dirt from accumulating.

 

Deep cleaning

Every three months or so, you can use soapy water to thoroughly clean the headlights to remove dirt on the surface of the lampshade. After long-term use, the surface of the headlight may oxidize and turn yellow. You can use a special headlight repair agent or abrasive to wipe and polish according to the product instructions to restore the transparency of the headlight. After the final cleaning, you can wipe the headlight with a special polish to keep it transparent and bright.

 

Inspection and cleaning of the headlight inside

Open the hood and check whether there is fog or water inside the headlight. If so, find out the cause and deal with it in time, such as replacing the sealing strip. For internal dust, you can use a compressed air can to blow it away.

 

2. Replace the bulb in time

It is recommended to check the brightness of the bulb when the vehicle has traveled 50,000 kilometers or about 2 years, and replace the bulb with insufficient brightness in time. When replacing the bulb, choose the original or professional brand bulb with reliable quality.

 

3. Check the lighting system

Regularly check the working status of the entire lighting system to ensure that the low beam, high beam, turn signal and other lights are functioning normally.

 

4. Precautions

Do not use overly irritating detergents or brushes to avoid damage to the surface of the lampshade.

Do not use the high beam for a long time, which will accelerate the wear of the bulb and lampshade.
If you need to replace the headlights, it is recommended to choose the original matching xenon headlights to avoid unnecessary risks caused by modification.

 

5. Other suggestions

Headlight cleaning function:

If the vehicle is equipped with a headlight cleaning function, you can use glass water to clean the headlights.

Soapy water cleaning:

Mix soap and water and wipe the headlights with a rag to remove dirt and oil stains, and prevent the headlights from yellowing.

Liquid wax:

After cleaning, you can apply liquid wax and wipe with a soft cloth, which can not only protect the headlights but also remove small scratches.

Professional cleaning agent:

If there are stubborn stains on the lampshade, you can use a special headlight cleaning agent.

 

The cleaning and care of car headlights is very important, which not only ensures the safety of driving at night, but also prolongs the service life of the headlights. Cleaning the headlights regularly and paying attention to the maintenance of the headlights can effectively prevent the headlights from yellowing and reducing the brightness.
