I took it to a technician. He told me he cleaned it with a brush. I paid €35. They became like new. After a year, they are much worse than they were before the cleaning.

It did the job, but after 3 months the headlights started to get cloudy again. It's good, but for long-lasting results you need a special sealant

when I applied it by hand, yes it did clean and shine the headlights, but when I used a polishing machine the result was completely different, the headlights became almost like new. the only downside is that it needs to be applied every 3-4 months!

To be honest, I didn't expect it to do anything. The application is very easy, even by hand. First, clean the headlights, then rub with the cream using a microfiber cloth, and finally rinse with a clean microfiber cloth. The whole process takes at most 10 minutes. We'll see how long it lasts. The headlight in the photo was the worst and still has a bit of cloudiness, but it's on the inside (negligible though). The other headlight looks brand new.

After 2 minutes of wiping, perfect (glass 20 years old)

Since it's my first time using such a product, I really liked the result. With a drill screwdriver and a sponge to avoid rubbing with my hand, the results can be seen in the photos. I don't know about the durability as I just did it, but I assume if you rub it with water sandpaper first and then apply a polish, it will be better than new. Very good for the price

The simplest thing available for headlight restoration that works. Only a microfiber cloth is needed. In a car that is in a garage and not exposed much to the sun, the initial restoration lasted about 1 year. Then when they started to fog up again, I just went over them one more time and they became clear again like before.

For the money, quite satisfactory. Removed the yellowing from the headlights. Maybe with a couple more hands I would have had a better result

With a few euros and patience, the result is good. With sandpaper 600-800-1000-2000 water and one hour of work.

This cream left me satisfied.... I started with sandpaper 400-1200-2500 by hand, continued with sandpaper 3000 on a drill and finally applied the cream with a drill polishing cloth.. They became almost new.... It requires patience in sanding and not rushing the whole process to see the difference.... It's worth it....

It does what it promises.
I managed to clean the headlights with a microfiber cloth and minimal rubbing.
Awesome product.

Personally, I was not satisfied. I expected my headlights to be cleaned based on the comments. I bought it, followed the instructions, and although they did clean to some extent (50%), it did not work where the problem was more intense. Maybe if I use sandpaper as some suggest, it will do an excellent job, but according to the instructions, it did not. The yellowing is gone, but the "haziness" in several areas did not go away even after the second time and it is very noticeable.

Very good product with approximately 80% performance compared to the initial state. I used it by hand only. I think it will have better performance with a brush.

If the headlights are too yellow for the job to be done correctly, they need to be sanded with sandpaper. Even if you don't sand them with sandpaper, though, enough fogging will be removed and the result will be okay.

Amazing, it does what it promises.. it made the yellow lights look like new.. and the more regularly you use it, the more they return to their original appearance. I will buy it again!!!

Applied with Meguiar's sponge 40 days ago. The result continues to be incredibly impressive even today. I believe the headlights will maintain their shine for quite some time, we'll see...

The difference is evident. We apply the cream with a cloth with strong rubbing, wipe with another clean one.
I don't know how long it will last, but the bottle has enough inside for many repetitions.

Excellent at what it does. On yellowed headlights that are 15 years old, I applied a small amount on a microfiber cloth, about the size of a bean, and quickly rubbed it by hand. It made them transparent like new. Obviously, the composition reacts with the oxidized varnish of the headlight and removes it, without removing the good varnish of the headlight. I repeated the process and they became very clean.
Update 19-09-2023. After 2 summer months in the sun, the headlights are starting to yellow again. The cream essentially removes the yellowed varnish from the headlights.

I bought it for 8 euros and experimented with it. I didn't have any hopes that it would be able to improve the car's headlights, which were completely blind. With the first application, I saw that it did an incredibly good job. The quantity in the packaging is enough for maaaany applications. It's the best option for anyone who doesn't want to deal with sandpaper and varnishes (which definitely do a better job).

Well... First of all, let me say that I had my headlights done by a professional 4 years ago. Unfortunately, he couldn't bring them back to 100% because the damage was severe. I bought the polish without expecting much, and you can see the results for yourselves... Restoration is 95 if not 100%!

I should note that the photos do not do justice to the result!

Very good job for amateur use

Use with a simple cloth and rub for 5 minutes. In the photos, one lantern is after using the product and the other is before using it.
For its price, it is very good considering how easy it is to use and the fact that the quantity in the packaging will last you for a long time.

Now we just have to see how long the result will last.

The product does its job just fine, although the result depends on the condition of the headlights. In my case, which were very worn out, a simple application and wiping with a cloth did almost nothing, but it wasn't the cream's fault. My headlights were in bad shape, with the varnish peeling off in many areas, there were small scratches, marks, and they were quite yellowed. So, I decided to dedicate two hours to initially go through the process with sandpaper. I bought the 600 - 800 - 1000 - 1500 - 2000 grits in order, and I sanded my headlights well with them. Then, I applied the cream according to the instructions and the result was very good. If I had extra money, I would also buy a clear spray varnish to make the headlights look like new with a long-lasting result, but even so, I am satisfied.

Applies very well to headlights that have not been cleaned/polished, etc. before. The process is simple: use a microfiber cloth and apply the polish in circular motions.

I applied the product with an application sponge and wiped it with a microfiber cloth. Good result on slightly yellowed headlights, about 85 to 90%. It doesn't scratch. Next time, I will try using a very fine sandpaper before applying it, and I believe they will become like new.

It does what it promises. It took 10 minutes for each light with slightly yellowed lights. First, wash with kitchen paper to remove dirt and foreign bodies. Then, confirm with a microfiber cloth and lightly rub until the yellowing is gone. In case of intense yellowing, repeat the process with a cloth and cream.

I did not like the result of it. The truth is that before buying it, one headlight after gradual sanding with 3m trizac sandpaper, it shined with autoglym paint renovation, unrelated to the headlight, but really the plastic became crystal clear!! When I applied the turtle wax on the other one with the same preparation, it left a very slight haze of about 15%. I'm not saying that the product is not good, maybe it didn't perform as it should with my own process. Maybe it doesn't need any sanding with sandpaper at all.

Without sandpaper, with 2 minutes of rubbing with a towel.

I used sandpaper 400/600/800/1000/2000/3000 and then polished with a sponge on a drill. I didn't dare do it without sandpaper, I considered it pointless.

Easy to use, without complicated procedures.
On the first try, I wanted to test it on a very old bike that had no indication on the dashboard.
After 5 minutes of rubbing, it started to clean. It really does a great job.
The second try will now be on the car, and I will come back with my impressions.
