Mold & Mildew Stain Remover for Natural Stone 24 Ounce Spray

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 ❤️

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.

I do house cleaning for a living. I've tried everything from chlorine bleach to peroxide etc. to eliminate mildew and pink slime. Nothing works. But this product has been a huge game changer! I'm amazed how the black mildew just disappears with minimal scrubbing! I'm using it on multiple jobs now and highly recommend this cleaner!

This was great for mildew on my marble tiles. Mold not so much. But to be honest, the mold is growing behind the silicone caulk. So it probably just isn't making contact with it. Some day, I'll rip out the caulk and try treating the mold. Stay tuned....

We had just remodeled our bathroom and I use the shaved pebble for the flooring in the shower so I was thrilled to see there was a product that wouldn't destroy this natural stone but would do the job of keeping control over mold and mildew. So far it's doing a great job and I presume that will continue to do so. Pleased.

I’ve used this for years, but the last bottle I purchased has absolutely no clean smell. I’ll admit the other bottles had strong smells, but this bottle has no odor, only soapy suds. I liked the fresh clean smell. Not sure what was put in this bottle???

This product immediately removed the orange mold/mildew stains in our stone shower. I followed the instructions carefully, and I rinsed it thoroughly when I was done wiping, and the result was amazing! I am very happy with this product and will buy again.

At first this product seem to be exactly what I was looking for. I could see that it was removing the mold and mildew from my shower floor which is marble tile. I was using it mostly along the perimeter grout lines but then I sprayed it more directly on the marble tile. After a few uses the orange spots increased and also notice that it made an imprint/discoloration on some of the tiles. I also noticed that the cloth I was using to clean with started to look like I dumped a cup of bleach on it. Needless to say I won’t be using this on my marble floors and I should have known better because it had a bleach smell to it.

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!

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.

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.

the stain in my counter didn’t come out.

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.
