Black Diamond Stoneworks Natural Stone Cleaner - Limestone, Slate & Travertine Cleaner - Natural Stone Shower Cleaner for Marble - Concentrated PH Neutral Stone Floor Cleaner - 1-Gallon.

Works fantastic on my slate tile floors.

This works very well! I have tried so many ways and solutions to clean our bathroom tile, to no avail. This product has cleaned it very nicely! I definitely recommend this product!

We have travertine floors and this cleaner works wonders on keeping the stone in beautiful condition. it also helps in keeping the grout clean, although it does take a little additional scrubbing with a hard bristle brush.

Doesn’t do much for grout but our natural stone mosaics look great

This works great on my travertine floors. It never leaves any residue and looks wonderful evertime.

So far doesn't seem to be working much or how I'd like it to, stone dinge looks slightly cleaner, definitely doesn't take stains away

Cleaned bathroom travertine floor beautifully and easily. Would have liked smaller quantity since it’s so concentrated.

The product does not work well on years old problem on shower travertine tiles. Disappointing.

Did a very good commercial job!

Best thing that ever happened to our travertine shower and sink tiles. Quick, gentle, smells very nice. Can’t wait to clean again ..

excellent must have for italian marble. 5 months since i have purchased totally satisfied. my house is always shining like mirror

Don't do what says

I buy this for my office; we have a polished cement floor. It works well and you don't have to use very much (according to my cleaner) I will keep buying this as long as we are at this location.
