How to maintain and prolong the life of car headlights at home
The lighting system is one of the necessary and important parts of any car.
But over time, there are many problems that can affect the lighting ability of the lights, reducing operating performance and thereby reducing the driver's visibility.
With just a few common tools and cleaners, you can clean your car's headlights at home and keep them shining.
The first and simplest method is to use glass cleaners with a soft cotton cloth or microfiber cloth to clean the lamp housing. The lamp surface should be cleaned when it is cold, that is, when the car is turned off and away from sunlight for a period of time.

If the glass cleaner does not work, try mixing toothpaste and baking soda and apply it to the surface of the headlight, wait a few minutes before wiping it off. For best results, repeat this process frequently. The toothpaste acts as a cleaning agent, while the baking soda mainly helps increase the adhesion to the surface, making cleaning more effective.
If you need a little more cleaning, you can try a mixture of lemon and baking soda. First, squeeze the lemon juice into a bowl or cup, then add a moderate amount of baking soda and stir until the mixture is thick, but not stiff. Next, rub half a lemon all over the surface of the lamp shell, then apply the lemon-baking soda mixture and wait a few minutes before cleaning again.
If the above mixtures do not bring the desired effect, try a mixture of vinegar and baking soda. Compared to lemon, vinegar has a higher acid concentration and will clean stains and insect remains on the surface of the lamp more effectively. However, be careful when mixing these two things because it will cause a foaming reaction. So it is best to add each small spoonful of vinegar to the bowl of baking soda slowly and carefully.
When all the above cleaning methods fail to remove stains, it is time to use specialized chemicals. Although more expensive, these chemicals will definitely clean the surface of the lamp effectively. However, you should avoid direct contact with the chemicals. Apply the chemicals through a cloth and wear gloves.
In addition, users can also use anti-rust chemicals to remove stains on the surface of car lights, but should avoid highly corrosive chemicals.
In addition, you should also have your lights maintained at garages. Scratched, faded, or stained lighting systems can be revived after being polished by qualified technicians with a chemical mixture and wet sanding machine.
Finally, if the above solutions still do not solve the problem, consider replacing the lamp housing as soon as possible. This should be done at the genuine service workshop to ensure the best quality, although the cost may be higher than outside garages.
Why should car lights be maintained?
Ensure the best lighting efficiency
Regardless of the brand of your car lighting system, whether it is made from high-end or common materials, it has a certain lifespan. In addition, frequent exposure to the outside environment also significantly affects the quality of lighting.
After a period of exposure, UV rays from sunlight and temperature changes will oxidize, causing the lamp's glass surface to turn yellow or become cloudy. Not to mention, condensation inside the lamp can cause electrical system errors, affecting the light quality of the lamp.
Therefore, checking, cleaning and maintenance will help the lights always maintain a stable operating state. Thereby contributing to increasing the life of the lights as well as ensuring safety for vehicle users.
Fuel efficient operation
Today's modern advanced lighting technologies allow users to choose fuel-saving support products such as laser car headlights, LED car headlights, LED car bulbs, etc. However, car lights only function effectively when operating under normal conditions.
If during use, the car lights have system errors or are damaged, these functions will be significantly reduced. Periodic maintenance will help detect and promptly fix these errors of the lighting system. Thereby contributing to limiting the waste of fuel when using car lights.
Ensure aesthetics for cars
After a period of time, the car's headlights will be affected by the external environment, become yellow, cloudy, and even have dust and fog inside the glass. Although it is only a small part, its location at the front of the car makes the lighting system have a great impact on the aesthetic beauty of the car.
