I used wet sandpaper with grits 600, 800, 1200, 1500, 2500, and 3000. I sanded each headlight for about 3 minutes with each sandpaper. Then I wiped them with a towel to remove the moisture, let the lamp warm up for about 8 minutes, and then went over the headlights. The result is like new.

The process of sanding with wet sandpaper is unbelievably difficult. Everyone says sand, do this and that, they throw around the successive grits and whoever can handle it. You need to know HOW you sand, how many grits you need to use, HOW MUCH pressure, etc. The whole result depends on the preparation, which for me turned out to be extremely difficult. You do learn something, but there's a lot of fuss over "nothing." At this price, NOT EVEN as a joke.

It has everything you need, does an amazing job.
You need to search on YouTube on how to do it, move slowly and use GLOVES - GLASSES - MASK.
If you inhale it or it touches you, it’s not the best thing that can happen to you. It’s enough for many headlight applications; for me, on 2 Jazz 06 headlights, it used very little and required persistence in some spots.

It is what it promises. If you do careful preparation with the sandpapers, the result will be fantastic. For very cloudy headlights, start with sandpaper 600, 800, 1000, 1500, 2000, 3000. For headlights in relatively good condition, sandpaper 1000, 2000, 3000, all wet. Wipe well to dry and start the process.

So guys, amazing product, I won't mention how it's done, there's a video on YouTube... the only thing I'll mention is to wear gloves next to you, don't let it spill on your hands, it's extremely toxic! Be careful when opening the bottle!!!

It does a very good job. You will need to sand the headlight well so that it fits perfectly, otherwise very good, I recommend it

It needs good sanding to remove the factory membrane, in case the headlights are not too bad. I followed all the steps with the sandpapers as instructed, but in some spots at the edges the membrane didn't come off, and the liquid can't be applied. It worked just as well as a polishing paste. Time will tell how long it lasts before fogging up again.

The device is pretty lousy, the cap with the lamp doesn't fit on the steamer unless you remove the rubber it has, otherwise it leaks and leaves a gap. The hole is probably not well processed and creates condensation which drips small drops onto the headlight, but when you pass the steam over the drops they evaporate without leaving marks, but if you try to wipe it by hand, it leaves a mark. Basically, they buy the device with the liquid from Chinese shops for about a fiver and sell it for 40+++€€.... As a device, this one is not worth the money. As a process, yes, it's worth it.

I bought the whole set from China ali for 10 euros. It did an amazing job. A very important tip when you bring the lamp close and it releases steam is not to touch the tip of the lamp on the headlight because the steam creates a type of film and leaves lines and then it will need polishing again.

Christ is Risen! It really does a great job; the lantern went from foggy and yellow to like new!

Very good product and the result is excellent, after a good sanding with sandpaper, I sanded with 800, 1500, and 2000 water) as seen in the photos they became new!!! time will tell how long it will last.

Very effective, with the right preparation they become like new! Now we need to see its durability! Care is needed regarding its use because wherever it falls it leaves marks that do not come off. Also, for some reason, it was causing liquid to rise in the tube along with the steam, resulting in two drops falling on the headlight, which looks a bit bad up close. I might fix it later or the next time the process needs to be done again.

Very good product in terms of performance, just the hole it has for the fumes to escape is very small, resulting in pressure building up and the cap "blowing" off with the liquid, causing everything to splatter everywhere (needs caution). If you make the hole a tad bigger, the problem is solved AND it covers a larger area of the lamp when you apply it, which means the job gets done faster. Also ALWAYS wear gloves and a MASK because it won't come off if it spills on you and the fumes cause significant damage.

It does an amazing job, we really saw a huge difference in the headlights, they became better than new and we have much better visibility at night of course, now that they are polished. It does what it promises as a product, now the only thing left is to see how long it will last, I will come back with a new review when the headlights need cleaning again. I’m uploading a few photos to show you the result before and after.

You take the water sandpaper, you rub, you dry, and the little lamp then does its job, the result is amazing, like new!!!!! the only solution, now it remains for time to show its durability.

Amazing result as long as it lasts as promised

It requires attention when using it, it does what it promises, very good result, how long it will last we will see.

Excellent product. It cleaned the headlights of the Grand Vitara (they weren't in very bad condition). However, I didn't expect it to work so well. There was a lot of material left over, so it’s enough to do more than one pair of headlights.

The result is very good; we will see about the lifespan. I hope they don't yellow in a short period of time and that they last over time. I give 4 because I don't know how long they will last

Very good and easy application! The lantern becomes very good. The like-new condition is relative since the signs of time do not go away! But it becomes clear again and performs like new! It requires very, very good sanding with water sandpaper; I started with 800, 1200, 2000, 3000, and then you apply the lamp. Because a "craftsman" had damaged the lanterns previously, I did 4 sanding cycles until it reached this point. And again, it needs more, but it's okay. So for anyone who doesn't get it right with the first sanding, don't be afraid; go through all the sandpapers again from the beginning, more intensely, more persistently, and maybe with less water, and then again with the lamp. Very good result; now how long it will last, time will tell! It is worth the money anyway! If you think about it, it's for many lanterns!

very good
we'll see how long it lasts

The headlights of the car, which is 22 years old, were terrible. I sanded them carefully with 800, 1500, 2000, and 2500 grit sandpaper and then used steam on them, and they truly became like new. You should give great importance to the preparation you will do with the sandpaper. Don't rush if you want to have the best result.

Although I had doubts about the product, it turned out to be very good. Now, we'll see how long it will last

I forgot to take it off (before)! But I think it doesn't need to be removed!!! They became new!!!

perfect, of course it requires the appropriate sanding with sandpaper

I simply sanded with a 2000 and 2500 grit sandpaper and then applied the polish

The pictures speak for themselves, I believe the job is easy, wet sandpaper starting with 600, 800, 1500, 2000, 3000, clean well, dry, apply this special liquid (mask gloves even in an open space) and the result is amazing, let's see how long it lasts

The result it offers is spectacular. Very easy to use. The only thing left to see is its durability over time.

I bought it to test if it can do a better job than the classic way with sandpaper and polishing. It really does a superior job! It removes marks that don't come off with polishing and buffing, especially in difficult areas. They also look like new in the light, with a shine like the original coating when it's new. Don't expect it to fix plastic breakages due to the low quality of the transparent cover, but it easily removes oxidation and such. For two headlights, fill the sprayer about 3/4 full. Also, be aware that wherever the liquid falls, even outside the device, it immediately wipes off and doesn't come off. I will definitely buy it again and get a refill!
