POLISHING THE HEADLIGHTS WITH TOOTHPASTE

Send

Modern headlight glasses have long been made of plastic, not glass. This replacement has one significant minus: with a long operating time of the car, the glass at the headlights begins to become cloudy and loses its transparency. Hence the diffusion of light beams, there is no clear facet of lighting, as a result, only blinding light for oncoming cars and no sense from the glow of headlights over a long distance.

Why does the headlamp glass become cloudy and yellow?

The thing is that plastic, unlike glass, does not have such hardness. During machine operation, various mechanical particles act on this glass: small pebbles, coarse dust, sand, tree branches, etc. All these particles and objects leave microcracks on the glass, which are not visible to the naked eye. Yes, even if you brush away the dust from the headlights with a dry rag, this will also cause micro damage to the glass. As a result, dust and dirt accumulate in these microcracks, the glass becomes cloudy and yellow.

Toothpaste polishing

To get rid of this drawback you need to polish the glass. Polishing will remove the upper micro layer of plastic along with cracks, smooth out all the bumps.
For polishing glass headlights, we will not use scarce and expensive polishes. We'll get by with regular toothpaste. Yes - yes, toothpaste perfectly polishes surfaces, and it doesn’t matter if it is metal or plastic glass.

Headlight polishing process

It is not necessary to remove the headlight from the car! I just did a major overhaul of my car, so I took it off, you can repeat my process without removing any glass or headlights.
The first thing to do is to clean the headlight from dirt and dust in the usual way. Sprinkle the headlights with any detergent and wipe dry.

If you have a choice of detergents, then preference should be given to one that contains isopropyl alcohol in its composition.
Then apply the toothpaste, smear the fats. And we begin to polish the usual towel, which is not a pity. I polished by hand with quick movements, but if you have electric polishing machines, you can apply them. In time, I rubbed the spotlight for about five minutes without stopping.

Next, wash everything off with water. Again, sprinkle abundantly with detergent and wipe the glass with a dry towel.

The result is noticeable, and I like it. Repeat polishing with toothpaste.
After the second polishing, the result is better, and a yellow coating is still visible on the towel, despite re-polishing.
