It does an amazing job!! You spray it on the fireplace glass, leave it for half a minute to work, and then with two pieces of newspaper nothing is left!!

I have tried at least 5 others. This one has the best result. I highly recommend it

It does its job but the acid smells very strong and the gun has some problem and every time I spray it splashes back onto my hand

Very good. It cleans the fireplace glass very easily no matter how much soot there is. Personally, I have transferred it to a spray bottle from another similar product (its own does not spray properly) and I am very satisfied. I recommend it. Just put it in another spray bottle.

Unbelievable how easily the glass was cleaned! The difficult spots needed 2-3 sprays but generally no scrubbing at all, just wiping over with paper

it is very liquid, so it does not stick easily to the fireplace glass
if you manage to make it stick, it cleans well

Very good! Be careful not to spill it and leave it on the tile/wood around the fireplace because it will corrode it.

Top! We had been struggling for a long time to find something to clean the glass on the fireplace and finally we found this. Amazing.

Fast, simple, effortless! The glass looks like new, in 2 minutes...

works perfectly, the moment you apply it to the fireplace glass it washes away the soot and stains .

The product is fantastic. It removes soot very easily. To avoid using too much product, spray 2-3 times onto a damp paper towel and you will do the same job.

One-way street!! Super value for money, it immediately removes smoke and dirt from the glass. I have tried products that did absolutely nothing, and I had found another German one that worked but was noticeably more expensive. I decided to try this one based on the reviews I read and I was thrilled with the result! I hope they never change the formula

The best thing while I have used 2-3 other similar products, it cleans 80% of the blackness with just one pass and with a light scrub afterwards it shines.

You spray, leave it for 2 minutes, wipe, and that's it. In fact, my glass had accumulated soot for many days and still, there was no need for even a second spray or scrubbing. I highly recommend it!

Cleans perfectly and quickly! Very effective. It shows in the photo how it was before and how it cleaned (up to where the hand could reach :)

Pen makes the glass.

Attention! Corrosive! In an energy fireplace that came into contact with the painted metal, the paint came off and caused rust. Better water and ash.

I tried several cleaners for the fireplace glass. This one you spray, let it sit for a minute, and it removes everything very easily. Only its sprayer sprays in foam form. I would prefer it to spray in a spray form. However, you can change the sprayer and everything is fine.

I bought 2 to clean the glass of my energy fireplace. It does what the others say without much effort. You spray, wipe, and you're done. Minimal rubbing with paper towels on the spots that didn't clean on the first go. I didn't wear gloves, I think it's not necessary. I will definitely buy it again.

Excellent product if the glass is cleaned daily, if there is a lot of smoke residue it needs to be sprayed multiple times.

Very good cleaner, really in 5 minutes it has removed all the dirt from the glass without much scrubbing and with minimal amount. Excellent!

Very good product does what it promises. You leave it to act for a minute, wipe it with a cloth and the glass sparkles. The only negative, as previously mentioned, is that it could spray with a wider dispersion to avoid splashing.

Magic!!!! Energy fireplace, application 2 minutes and simply cleaning!!! No rubbing-no rubbing-no rubbing!!! Very good!

The best in its category... simply with the others you waste your time and your money as it is also very cheap.

For energy fireplace glass, this is an excellent cleaning product without scrubbing and without leaving it for even 5 minutes... spray it and a microfiber cloth and the glass becomes brand new

Excellent!!!! It cleans 90% in the first pass and then you repeat 1 to 2 times to make it new again!

Very good product, if you leave it for 2-3 minutes to act, the soot in the fireplace glass disappears with one swipe. Another thing that impressed me a lot, besides the fact that it cleans well, is that it has a very good spray, meaning it empties until the last drop

A mediocre overall product that I tried out of simple curiosity. Apart from its very low price (which makes it popular among most people), it cannot be compared to much more qualitative and effective products (of similar cost, of course, which overall are more advantageous though).

For some casual use, like a backyard fireplace and grill, it could be used.
The absolute drawback is the sprinkling mechanism instead of a regular sprayer.

Good result
It doesn't smell when you spray it, but it smells when you light the stove. I bought one from Jumbo, it does almost the same job, but it doesn't smell when you light the stove.

The product is simply fantastic! One spray and the smoke clears immediately. You should definitely get it without a second thought
