How to Clean Car Headlights?

Car headlights cleaning steps are: 1. Remove the headlight assembly; 2. Take out the bulb; 3. Add an appropriate amount of weakly alkaline cleaning solution into the lamp cover, then use a suitable long tool with a towel or soft brush attached to its tip to gently scrub; 4. Rinse thoroughly with clean water and let it dry naturally or use a hair dryer to dry (keep the temperature low and ensure it's completely dry); 5. Finally, reassemble everything to complete the process. Car headlights, also known as car front lights or car LED daytime running lights, serve as the 'eyes' of a vehicle. They not only affect the owner's external image but are also crucial for safe driving at night or under bad weather conditions.
When I clean my car headlights myself, I always start by preparing the tools: a bucket of warm water with a small amount of mild automotive soap, a microfiber cloth, and a bottle of clean water. First, park in a shaded area to let the lights cool down to prevent damage from thermal expansion and contraction. Then, dampen the cloth and gently wipe the surface of the lens, avoiding excessive force to prevent scratches. After that, rinse off the soap with water and thoroughly dry with a dry cloth. During cleaning, check the lens for any signs of yellowing. If it's minor, you can use a polishing compound, but avoid products containing ammonia or acids as they can oxidize the lens. After cleaning, the headlights will be brighter and clearer, making nighttime driving safer. Remember to clean them once a month to prevent dirt buildup and yellowing. I've been doing this for several years now, and the improvement is really noticeable. Plus, it saves money by doing it yourself.
As someone who has worked in the automotive industry for many years, I recommend professional services for headlight cleaning as their high-pressure steam equipment can thoroughly remove stubborn stains without damaging the headlight body. If you choose to do it yourself, use a neutral cleaner sprayed onto the headlight surface, wait half a minute for the stains to dissolve, then wipe with a soft sponge and rinse with clean water. The key point is to avoid direct high-pressure water flow to prevent water ingress and short circuits. After cleaning, check the sealing performance and repair any leaks immediately. This method is simple and cost-effective, which I often recommend to car owners, and it works even better when combined with regular maintenance to extend the lifespan of the headlights.
