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.

This is the best stuff i have used to remove stains in granite and I have tried everything, whether is was a poultice, it was 24 or 48 hrs, it was wrapped or unwrapped. I have used every mixture combination as well as straight on products and a heat gun. Stone tech did the best job! I had black granite before and never did anything. When I purchased the light granite, no one said it would stain and I never even thought it could, boy was I wrong. I also was not advised about sealing it constantly and I did not, so the apron in front of my sink turned black and gray. Terrible looking and terrible spot. Stone tech has managed to remove a lot of it where nothing else, except the heat gun, but that can damage the stone. The smell is a strong citrus especially until it drys. If you decide on a light granite, my advise is to seal it at least every 2 months.

I created a horrible mess by using pipe dope putty that contained mineral oil to seal the flanges on my faucets. In less than a week a dark stain was creeping from under the fixtures. When I took them off for a look I could see that under pressure the oil had penetrated about 1/4 inch deep! After reading a lot of d-i-y poultice ideas, I decided to pick up one of the clay powder products. These are made of calcine clay and are pH neutral and are mixed with water. After two applications the stain was substantially lighter, but still deep. That's when I ordered this product. The Stonetech poultice pulled out the entire stain in one try. Amazing! My granite is a light tan, and I have noticed a shadow beyond the original stain zone (others have had such an experience). That stain seems to be the remnants of the solvent. I put a fan on the sink and after 3 days it's faded to the point where only I know where it happened. If I was really concerned at this point, I believe that another clay and water poultice would pull out the last of the shadow. In several places I have heard people remark "know your stone". Wow is that the truth. When you buy a granite top, get some spare pieces of the material that you can use for future experiments before treating a stain on your real countertop. Also, don't assume that the installer did a thorough job of sealing the top because mine did not! I wanted to make a few remarks about poultices. The reason they work is because they create a gradient boundary that attracts the stain from the granite. To do this you need to have the region full of stain in contact with a material that contains no stain, and has the propensity to aggressively absorb the stain and any added fluid. In physics terms this is a combination of osmosis, diffusion and suction. The reason poultices work best when mixed with a liquid is that the liquid helps to bring the absorbing agent (such as talc or clay) into closer contact with the granite, and also the liquid helps to mobilize the stain within the granite. It is very important to have the poultice overlap the stain because otherwise the stain might migrate away from the poultice either by repulsion (oil versus water) or by dilution (i.e. the staining material might join with the liquid and flow somewhere else). I think that stain migration is a bigger risk when the liquid in the poultice is compatible with the stain. So, there is a bigger risk of migration with an oil stain and Stonetech than there is with an oil stain and water-based clay. That's way I strongly recommend you try to remove as much as possible with a water-based clay before using Stonetech. However, I hope this is my first and last stain disaster, so I am only speaking from one experience.

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!!

Does a fair job. Applied the product to some dark wood stain I accidentally dripped on concrete and sandstone around the exterior of my house. I was staining some cedar posts and careful as I was, I still managed to have some drops. Looking online, this came highly recommended. Applied and left product on for 72 hrs. The removal was a chore. Scraping off the excess was easy enough, but be prepared to take a wire brush with much effort to remove the white stain this leaves behind. I eventually used a wire wheel in my cordless drill to save my arm from all the brush work. Then wiped with a damp cloth to try and remove the white powder from the area. After it dried I was underwhelmed with what was left, as the stain was still visible, just faded a bit. I hesitate to reapply product due to the effort required to remove product. I’ll live with it as it is.

I had mineral oil stains on my white granite from the plumber using the wrong putty to install my faucets. The granite guys recommended Maangia macha (a poultice), but this did not remove the stains after two applications. This product removed these stains in 72 hours when used as recommended. I don't know what this product contains, but I am a scientist and have a good guess based on what I observed. I think this might clarify some misconceptions on what this product can and cannot do. First, it probably contains an organic solvent(think toluene, xylene, petroleum etc) in order to dissolve oil stains. This solvent readily penetrated the thickness of the stone (within hours) and spread beyond the original stain (very nerve wracking!). So I am going to guess if your granite is sealed, this will work poorly. This substance appeared to be volatile and evaporated over 72 hours from the surface of the poultice, taking the dissolved oil with it. So if your cover up the poultice, this product may not work well. Four points: This should work on substances that dissolves readily into this solvent, it is not going to work on everything. Second, it needs to be able to penetrate the stone (stone should be unsealed, you can unseal granite with acetone, I think this may be what the granite guys use). Third, The poultice should not be covered. Fourth: It will take several days. I have to add that I am making an educated guess at this, I do not actually know what the composition of this product is.

Whatever complaints people seemed to have about this product seem to be things that no longer apply with the product in its current state. There is no obnoxious, constantly lingering, overpowering smell. You will notice about the same amount as you would from any cleaning product. Follow all the instructions, and chances are you'll lift the stain without a hitch. Had some oil stains on a granite countertop that I was certain would never come out. I tried every other homemade method, making my own poultice, but it never worked. This product worked, and was well worth the money. Felt like there was a lot of red tape between getting the product and even opening it wasn't all that easy, but that is understandable. Just something to be prepared for. Definitely recommend the bigger sizes as it will be much more convenient to have your supply ready to go for new stains. Easy instructions, did the job, was not a hassle. Crack open a window or use your stove fan or a stand alone fan if you're that concerned about the smell, but it really doesn't seem to be a big deal now in this iteration of the product as some people have made out before in the past.

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.

The product works great and the customer service from the store has been outstanding. I happily recommend them.

Muy bueno, quita las manchas de grasa como promete, lo recomiendo

service and product 5 star
