StoneTech Soap Scum Remover, Cleaner for Natural Stone, 24-Ounce (.710L) Spray Bottle (2 Quart pack)

Easy on my natural stone strong on mold it doesn't smell in comparison with other products.

Use this to clean my marble shower. It is pretty good. It is hard to clean a marble shower.

I found this product did just fine on getting rid of soap scum, and didn't damage my marble or limestone. It's a pretty mild cleaner, so you'll still need some elbow grease and one of those plastic scouring pads to really do the job. Also, a toothbrush is needed to get into the crevices.Pretty expensive for what it is. Don't know what's in it, but it smells like an ordinary ammonia based household cleaner. Those aren't recommended for limestone, so maybe this is just more dilute, or has a special ingredient or something. Either way, seems to work. Maybe worth it if you've neglected the situation for a while, but I'd try to find some other solution for regular cleaning.

I used this cleaner on Travertine to remove a number of soap film areas. The product left a white residue over the entire shower floor surface. I used a scrub brush and rinsed thoroughly as directed. I even repeated a second time as suggested on the bottle but the white film remained. The white soap residue is more widespread than before i used the product. Definitely not worth the money.

Cleans my tiles and soap scum from shower doors great

Great for natural stone such as travertine.

One bottle leaking when arrived

I like the product and needed it so I didn't want to return. But it leaked a lot during shipping. The label was damaged-peeled off and the shipping bag had quite a bit of the product in the bottom
