STONETECH Oil Stain Remover, Cleaner for Natural Stone, Grout, & Masonry, 1 Pint/16OZ (473ML) Can

Welcome to the natural stone support group.If you are shopping for this or similar products, you probably need more emotional support than you need a product to remove stains from your natural stones LOL.I've been there, done that. You have a remodel project going or waiting for your new home to be built. Time to make decision about your countertops. You fall in love with the natural stones. You are in a vulnerable state and fall prey to the lies natural stone companies tell.They make you believe thet the stones are indestructible, and that you are good to go once they are sealed.Lies...all lies...100% pure lies. But you don't know that yet because you are infatuated with your stones. They probably wouldn't sell anything either if they told you the truth, right?So you spend the big $$$$ and are happy because when the kitchen remodel is done or your new house is delivered, your countertops look breathtakingly beautiful.The honeymoon period is cut short the moment you see your first stain. It probably came out of nowhere too. What happened with the sealer? Wasn't the sealer good for for a few months at least before you needed to reseal the stones?Denial - Anger - Bargaining - Depression - Acceptance....you go through all of the stages of grief!Best piece of advise to anybody reading this: if you are thinking about natural stones for your countertops...just don't! Seriously, don't do it. It is probably the worst decision you'll ever make in your home...especially if you might think about renting your property in the future. Quartzite is the worst offender from all natural stones by the way. It is crazy beautiful but extremely high maintenance.Exceptions: natural stones "might" be ok if there are no children in the house, you are 100% committed to wiping every drop of water or oil literally right away (yep...even after the stones are sealed) and covering the stone portions next to stove each time you cook (yep...because any splash of hot oil or boiling water will go through even the most expensive sealer). By the way...companies that sell sealers are full of lies too!Having said all of that, Stonetech gave me the best results so far from all the products that I've tried. I have Quartzite, which is really a maintenance nightmare. The "removed" stains look similar to what a tattoo looks like after a tattoo removal: most of it is gone but you can still see the shade of it. This is better than having a full blown stain, but not 100% the way it was before.You may get better results with other natural stones. Again, Quartzite is extremely difficult to maintain even after being sealed properly with the best sealers.And this is the truth that natural stone sellers don't tell you: all natural stones are more fragile than they seem and ALL of them without exception WILL get stains.... even if properly sealed.You've been warned. Good luck with Stonetech. It is really the best product out there to remove oil stains.And yes...it has an incredibly strong citrus odor...though it is not as unpleasant as other reviewers state. Just open the windows for a little bit after applying them and you'll be fine.

We recently bought a house with beautiful charcoal gray granite. Unfortunately it had deep oil stains next to the stove (I could see through the side of the granite the stain penetrating almost 1/2"deep) and few other smaller stains throughout 4 sq. ft. section of the granite. So I decided to try this stain remover on the existing stains. I diligently followed instructions applying the remover. What I didn't realize is that the stain next to the stove and small others weren't the only stains we had - the whole granite section to the stove was evenly stained/discolored over time. When I peeled off the stain remover, to my horror, I saw several light gray circles - the remover worked too well.I ended up buying 3 more cans of this stuff and cover the whole section of the granite on each side of the stove (even the backsplash as it was darker than the original color). I know I should have bought at least 4 cans and I didn't have enough for 1/4" layer as instructed, so I ended up applying only 1/8" thickness on the surface. It worked! This was rather an expensive and risky experiment, but there are no more light gray circles. The whole granite section is lighter and matches the opposite side counter (I can't believe I didn't notice how much darker it actually was). The small stains are now gone. The only stain this did not remove is the deep one I was hoping to get rid of. It is much lighter than it was originally but it is still there. I do not fault the product for not removing it. This stain is so deep and has most likely "set in" for a long time. I would probably need to do several applications, but for now, we need our kitchen. This process took whole week, plus another three days for resealing the granite with StoneTech BPSS12-32 BulletProof Stone Sealer, 1-Quart.I learned a lot about the granite during this experiment. Like another reviewer said: "know your granite." I wish I had paid attention to the color of the granite throughout the kitchen counter and have noticed slight color variations. I would have covered the entire section from the start and didn't waste money. But the product did work and I am very pleased with the results.

I used this on two areas: first on a small spot that had recently gotten some oil drops on granite that was not sealed by the installers. It worked great (although smelled horrible). Encouraged, I applied the rest on my huge center island that had several large, but rather inconspicuous old grease stains. This had been sealed by the installers, but over the past six months, the kids had left butter knives on it and whatnot and there were some spread-out, but not obvious stains.The smell on a large area is almost unbearable. My kids and I could barely stomach being in the kitchen at all for the two days in was on the counters. After two days, we removed the dried white flakes and cleaned the area. It completely darkened the counters. Where the paste was has turned a light grey. Kashmir white has grey in it, and it seemed to intensify the grey and make large streaks. I really don't know what to do now. This mistake will probably require me to replace my entire island. I am so disappointed. It looked okay before, and I was just using up the rest of the can on some areas that were not bad, but could be better. Using this product will cost me over a thousand dollars. I very much regret trying this product. The product did not do this at all to unsealed Kashmir white, but it discolored my sealed section in a very bad way. Worse, since I applied I areas 1-2 inches larger that the original stain (per instructions), the "stained" areas went from 0.5 inches to 4 inches wide. Buyer beware!!
