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

I put this in the water of my Roomba and it does a great job. My travertine floors look amazing.

Works as advertised in used it when weather was 75 degrees. My tile looks great

Exceptional stone cleaner. Had some staining on my stone shower floor. I have been trying to remove it for months with various cleaners and solvents. Nothing seemed to work well. The Black Diamond product removed these stains and made the stone to look likre a fresh install. Highly recommended.

The application took care of leaf spots on my patio, but haven't had any tougher spots to deal with

I have over 2000 sq ft of natural slate tile. This product works great at a reasonable price.I can't compare it to other products since the prior owner also used this cleaner.

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

Prompt deliver. Works well for natural Travertine stone floors

Why did you pick this product vs others?:Did not work on my slate patio !
