Mold & Mildew Stain Remover for Natural Stone 24 Ounce Spray

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.

Eliminated the mold fast. Seriously surprised how well this stuff works. Best if you're working with porous surfaces, as it won't damage the color.

It worked soo good. I had so much mildew formed on my shower tiles and was worried i permanently stained them, but this made them white again

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!

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!

The product works well but the packaging for shipping is terrible. Do not have this delivered with other items. It leaked all over the other items I purchased (one being a cell phone charger!) and destroyed the packaging on my other items too. Not to mention that half the bottle is now empty, which is extra frustrating since the cost of the product is pricy.

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.

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.

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.
