I have used many types of hearth cleaners - this is the first one that I used that actually cleaned the soot off. You have to be careful to rinse well but so far I would recommend this product. I used a steam cleaner to get the residue off quicker. Using a wet sponge took too longHappy to find thisAmazing product. My pellet stove malfunctioned and my walls are covered in soot. After trying all the remedies posted on the internet, that did not work, I searched Amazon (which I should have done in the first place) and found this product. Ordered one bottle and tried it on a small spot with a paper napkin and the soot came off the wall so easy. So I ordered three more which should take care of the whole house.I do not plan on using it in the stove itself.This stuff cleans the inside of the wood burner glass with easeI thought I was purchasing a container with a spray nozzle so I could spray the product into our wood stove. There was no spray mechanism, just a screw-on cap. The product works great, but we had to locate our own spray nozzle to actually use it.This product removes all of the smoke and smudges on the pellet stove glass with ease. This is my second bottle.I wanted it to clean the glass on my wood burning fireplace. It does help, but requires a lot of elbow grease and still leaves much black behind. In addition any drops that fall to the slate hearth leave white spots that won't clean up.Doesn’t clean my stone hearth. The stone is porous and accepts the cleaner, but soot never comes up.Wear a mask. It smell terrible.
