Can Asphalt Cleaner Be Sprayed on Headlights?

Asphalt cleaner can be sprayed on headlights. Here is some relevant information about asphalt cleaner: 1. Main Uses: A new industrial-grade powerful cleaning solution designed for use in homes, cars, ships, and RVs, etc. It can effectively remove grease, road stains, car-induced ground stains, and stubborn grease around houses. Suitable for any cleanable surface, it can powerfully eliminate heavy stains. 2. Precautions: Asphalt cleaner has a pungent smell, which is inherent to its composition. It does not damage the car's paint because the composition of the paint differs from that of paint and asphalt stains. Asphalt cleaner can dissolve paint and asphalt, but it does not chemically react with the paint's composition. If you are concerned about potential damage to the paint, after using the asphalt cleaner to remove stubborn stains from the car's surface, you can wipe it clean with a soft cotton cloth dipped in clean water.

I used to be curious about this issue too, so I tried spraying tar remover on my headlights—it was disastrous. The lens surface immediately turned white, fogged up, and developed tiny cracks. Tar removers contain strong solvents like acetone or formaldehyde, which are designed to tackle stubborn stains but are extremely harsh on plastic headlight covers. Most headlights are made of polycarbonate, a fragile material that accelerates aging when exposed to such cleaners. I even tested the resistance with a multimeter and found that residual chemicals might seep into the circuitry, compromising electrical safety. After spraying, the headlight's transparency dropped, making nighttime driving visibility blurry and more dangerous. My advice: don’t take the risk. It’s better to spend extra time gently scrubbing with water and pH-neutral car wash soap, and maintain your headlights regularly to avoid accidents. If the lens is already damaged, you’ll have to visit a repair shop for a costly replacement—it’s shockingly expensive.

When I first bought my car, I didn't know much about maintenance and thought tar remover was a universal cleaner. I sprayed it on the headlights once, and the lens turned yellow and dull with noticeably reduced light transmission. Now I understand that the cleaner was designed for tires or the car body—it's too strong, and the plastic of the headlights can't withstand repeated corrosion. A friend of mine had a similar issue with his headlights and ended up spending thousands to replace them. For regular headlight cleaning, mild car wash soap or a damp cloth for gentle wiping is enough—don't cut corners by using harsh chemical products. After cleaning, remember to check if the lights are functioning properly to prevent moisture ingress and potential short circuits. From a safe driving perspective, clear headlights are essential for nighttime driving—don't let small issues lead to big troubles. Proper maintenance extends the lifespan of your headlights, saving you money and hassle.

As someone who frequently performs DIY car maintenance, I've tested various household cleaning methods. Using tar remover on headlights is absolutely not recommended, as the chemical solvents like benzene in it can react quickly and corrode the surface of the lens. I once tried spraying a little bit, and the headlight became hazy immediately—it was troublesome to fix. I recommend safer alternatives like a paste made of baking soda and water, which has a gentle effect and won't damage the plastic. Remember to clean with light movements, using a soft cloth to avoid scratches, as keeping the headlights clear enhances driving safety.
