After using the car for a long time, the headlight shade will not only turn yellow, but also have a very fuzzy layer attached to the surface, which will affect the lighting effect. How to restore it to like new? Some friends talk about insecticides, is that true? Let's give it a try.
Before cleaning, you need to find out whether it is yellowing internally or externally.
There are two main types of yellowing of headlights. One is that the inside of the headlights turns yellow, and the other is that the outside turns yellow. Yellowing on the outside is more common.
It is quite simple to distinguish. If it feels rough with your hands, then it is an external cause. If it's smooth, it's probably yellow inside. Today we are mainly talking about external yellowing.
Compare using different recipes
In addition to insecticide, we also prepared soap, WD40, and toothpaste to try, because we heard that these things can solve this problem. The tape headlight is divided into four parts, and these items are used respectively.
- Test whether the alkaline substance of soap can remove yellowing substances
Try soap first. So I heard that soap contains alkaline substances, which can remove the yellowing oxidized substances on the surface of the lampshade.
The reason why the lampshade turns yellow and mushy is mainly because it is made of PC plastic, which easily oxidizes and turns yellow over time, forming some small pits on the surface, where dirt gets stuck.
Wet it with water and soap, apply it directly on the lampshade and apply it evenly. Don't rush to flush it, wait for a while, let it stick to it for a while and then rinse it off.
- Experimenting with abrasive ingredients in toothpaste to see if they are effective
Next is toothpaste. I heard that toothpaste contains abrasive ingredients that can remove the oxidized substances on the lampshade.
Apply the toothpaste, spread it evenly with a sponge, and try to use some force to remove the oxidized substances as much as possible. Leave it there and flush again later.
- Experimenting with WD40 and insecticide effects
Next is WD40. As mentioned before, it has antioxidant and cleaning functions. Then there are insecticides, which generally contain some organic solvents that can remove oxidizing substances. Try them all.
- Protective measures must be taken when using WD40 and insecticides
These two things are very convenient to use, just spray them on directly. But be careful when using it, avoid touching your eyes, and wash your hands after use. Both of these two things are corrosive to a certain extent.
The test items all worked well, but toothpaste and soap would be better.
Finally, I started to rinse the entire lampshade clean with water, and found that these four things were still somewhat effective. It can be clearly seen that the lampshade is much whiter, and the yellowing phenomenon on the surface has also been improved a lot.
Once the tape in the middle is removed, you can see a clear difference.
But if you look carefully, the effect of toothpaste and soap is slightly better than that of WD40 and insecticide, so using these two things, the effect of cleaning headlights is not bad.
It's usually available at home, and it's pretty good. But if you think it's troublesome to apply it like this, just give it a try. WD40 is also a good choice, and it can also remove rust from other places on the car.
