Review: Got rid of mildew stains in my shower's stone floor -- stains that Tile-X couldn't eliminate - 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.
Review: After wasting money for years, found a product that actually works! - I have a stone shower in a bathroom that lacks proper ventilation so there is a constant battle with mold. I have tried dozens of products over the years and nothing has worked. I just used this for the first time and it removed the stubborn mold the first pass! I used a nylon brush to scrub the grout and corners so it did involve some elbow grease but I am thrilled how effective this product is. Beware, the smell is strong so open a window and have a fan running. I will certainly be buying more of this!

## Questions & Answers

**Q: Does this product also contain bleach? I have asthma and must be real careful of fumes.**
A: It doea not contain bleach. The ingredients are sodium hypochlorite, alkyl amine oxide, alkyl aminoacetate salt, and water.  The fumes are rather strong despite it not containing bleach. I would definitely make sure your room is well ventilated and work in small sections. It works great!

**Q: Is this made by dupont? the bottle says laticrete....**
A: Laticrete International purchased the Stonetech division of Dupont in 2014.  All labeling changed over to Laticrete the first of this year.  Same product, new owner with a slightly updated label.  Thanks!

**Q: does this work on ceramic tile please?**
A: I’m sure it will; I bought it to use on my marble tile so it would not be damaged. It works well.

**Q: Does this work on silicone?**
A: It may work but be careful to not wear down the silicone from scrubbing with the cleaner

### ⭐⭐⭐⭐⭐ Best Product I've Found For Natural Stone (Travertine) Products
*by S***H on May 6, 2016*

We live in Southwest Florida where the combination of high heat and humidity makes it ideal for growing mold and mildew. Getting it off natural (unsealed) stone is not as easy as you might think. Most of the products I researched will damage natural stone because of the Ph. People tend to forget that natural stone is porous and will absorb liquids -- and therefore show stains. Trying to use regular grout cleaner on marble will result in the marble edges touching the grout looking like someone buffed the sheen off it. Not good! After looking, researching, and trying several grout cleaning products, I finally found this DuPont Stonetech Mold & Mildew Stain Remover. It is a bit pricey but after several failures I was willing to pay a little more to effectively solve my problem. Our shower stall is composed of travertine walls and floors. Since it is in the corner of our master bath and has almost a floor-to-ceiling glass door, there isn't enough air circulation in it to prevent the formation of mold and mildew. Mold and mildew removal is pretty easy. Simply spray the mixture on your grout lines, wait a few minutes, and then scrub with a non-abrasive sponge or an old toothbrush. It doesn't take a lot of effort although stubborn stains will require a second treatment. The other tool that I've found to be indispensable in cleaning the shower is to use a clothes steamer. Anything that resists two treatments with the DuPont Stonetech product will easily be eliminated by using your clothes steamer. Just hold the steam head very close to the grout and the mold/mildew will disappear. And if there is still evidence of mold/mildew, try using a fine tipped scratch pen/sanding pen. Amazon sells the KTI-70550 for about $7.00. This essentially allows you to sand the offending mold/mildew off the grout while staying on the grout line and avoiding the marble edges. While using this cleaner, make sure that you have proper ventilation and use a mask to avoid breathing in the fumes. That strong smell that reminds you of bleach is sodium hypochlorite -- which is actually BLEACH. So take care to protect yourself and not damage your lungs. After using your clothes steamer for awhile you may decide that you get acceptable results (depending on how bad the mold/mildew is) just by using the steamer and avoiding the fumes.
