StoneTech Mold & Mildew Stain Remover, 24OZ (709ML) Spray Bottle

So after remodeling my bathroom, I had come to regret putting in a natural stone floor in my shower. It is so hard to clean I have literally thrown my back out scrubbing the mildew from the grout and walls. I saw the DuPont mold and mildew stain remover while scrolling through Amazon. I have tried every natural product , home remedies you name it I have probably tried it. Can’t use commercial chemical based cleaners for fear it would ruin the stone. I figured this said it was formulated for the real stone why not try it after reading some great reviews. Let me tell you Wow.. this product is a game changer for me. Super easy to spray on.. I let it sit about 5-10 minutes scrubbed it with an electric scrubber.. hand scrubbed a few spots between the tiles. It came off super easy. It seems to be super gentle on my tile. The smell is a bit strong be careful if you’re sensitive. I can’t believe the difference super happy with this product. Before and after is incredible.

This product is Amazing! Don’t hesitate to buy!! I used it on my Carrera marble shower and bathroom floor I have polished basketweave marble, which has lots of grout. It took away all mildew and grime. I left it on just a few minutes and used a small Nail brush scrub the grout. It came up like brand new. I have White grout. I have never found a product to use that was safe for my polished marble and the baking soda that was suggested to me just didn’t cut it. The smell is clean and no residue. I followed the directions which said rinse after scrubbing. This product makes me so happy to clean my shower ;) Thank you STONETECH !!! I’m going to try other products from them ❤️

After moving into our current home, I was hesitant to use my prior Mold Armor mold remover (which worked great for killing mold, but seems to be discontinued) on our current tile because I don't know what material it is, so I was worried it might be too harsh. The mold got bad enough I finally got around to looking for and trying a stone safe mold remover. This works well enough (seems to be a bit slower, but took care of the mold without issue) and doesn't seem to be causing any problems with the tile. The smell is also much less pungent than the Mold Armor one. Only thing is I still don't know what specific tile we have so I can't share that information.

Okay, I love this cleaner. It cleans my stone tile way better than anything I have tried. However, almost passed out using it. I’ve cleaned with tons of products and have never had that issue. Maybe I used too much? Definitely have a fan circulating air and open a window!

This product worked better than expected. I had some stubborn mildew stains in the stone floor of my shower. I had treated the stains repeated over the past few years with grocery store mildew products like Tile-X. Those products lightened the stains a little, but they were still very noticeable. When I first tried this product, I didn't think it was working better than Tile-X. But I let it sit for most of the day, and eventually it eliminated the deep set mildew stains in the stone. I don't know whether this product has different chemicals in it, or whether it's just thicker and therefore able to stay and work on the stains better. In either case, after one day (and repeated applications), the stains that have resisted me for years are finally gone. The product has a faint bleach smell, so I'm assuming that's the working ingredient. Very easy to use. Just spray, let it set, then rinse. If your stone is sealed, you'll probably have to use a scrubbing product first to remove the sealant layer, then apply this stain remover, then rinse, clean with an everyday stone cleaning product (like Granite Gold Everyday), then reseal.

Okay, hands down the best cleaner I have used for my tiles. We just redid both of our bathrooms. We have marble in one and porcelain in the other. The grout is still new, but starting to turn orange in certain places. Bleach is an absolute no. So finding products that don’t have bleach and work is a struggle. My friend recommended this one and I have to say I was surprised. I was able to spray the areas that needed tackling and followed with a soft bristle brush to brush the remaining stuff off. It worked really well in my linear drain which tends to get moldy quicker - for obvious reasons. Honestly, I can’t say whether it’s gentle. The product does advertise that it is. But it was easy to use, little smell, and cleans well. Overall, very happy with eh purchase.

Possibly the good comments come from people who used it in the grout, but not to clean the the surface or porous parts of the travertine. . In my case, a fatal result, it didn't removed anything. Wasted my money.

I like the product and it works well but for the price , it would be nice if this was packed better... I'm not sure if it just leaked or if the top is cracked somewhere , and it's still leaking as bottle wet after drying it off when i checked it a again. I'd give the product 4 stars , but I the packing 1

This product works! For years I have been scrubbing my grout and tile trying to get the orange color out of my grout. I have tried so many different products and nothing has worked. I finally came across this one and thought I would try. Look at the left half of the photo. That was after 10 minutes and a rinse. No scrubbing! This is the first time that my tiles have looked clean!

I removed mold and mildew from shower tile grout. Spray on wait 10 minutes and wash off!!! Amazing!

I've tried everything from all the big brands. If it had the word Mold or Mildew on the label, I have bought it and tossed it. But this actually took the gross away from the grout in my shower stall. Not 100% but still visibly cleaner. And no harsh smell - just vaguely bleach-y.

Read all information carefully and then apply. The smell is very powerful is the only drawback. Having said that make sure to turn on any fans that you have in the area. This is the best product that I have found for its purpose. I left it on overnight and all stains and mold were gone. I highly recommend the product. Shop arround because price differs greatly between sellers. This a market place product and there are no returns.

After having mould issues for a few years, Stone Tech Mould removal resolved the problem. We periodically reapply to ensure the mould doesn’t return.
