Black Diamond Stoneworks Marble & Tile Floor Cleaner Concentrate, pH Neutral, Streak-Free & No-Rinse Formula for Granite, Travertine, Limestone, Slate, Ceramic & Porcelain Floors (1 Gallon)

I was hesitant to use this on my penny tile shower floor. I didn't want to wear down the sealant in the grout or cause any issues to the tile. I had hard water spots on the tile. I started with a little diluted product and scrubbed. It didn't do much. I tried it again and kept scrubbing. I began to see an improvement. I tired it a third time and it was working. A little scrubbing and patience and it got it clean - without any damage to the sealant or tile. I'd use it again and recommend.

In my first use of this product, my floors looked so much better! It removed the grease and footprint issues much better! Love this product! A little goes a long way so very pleased with the quality! Thank you!

Black Diamond stoneworks is my preferred product for cleaning the custom stone in my home. I trust their products to clean thoroughly without damaging the stone surface.

Works great! Doesn't leave streaks or residue buildup. It's not a strong overpowering scent either!!

It's the best cleaner I've ever used Its very concentrated so it goes a long way Will definitely buy again

I've purchased this prior but in a smaller bottle to try. i can mop my porcelain floors snd it cleans well and no residue left after.

This cleaner works well for the price.

Works great on our tile floors. Pleasant scent and leaves no streaks. Good product.

Leaves floor very shiny and nice

This product is so easy to use. Just mop and done. No leftover residue.
