Black Diamond Stoneworks Ultimate Grout Cleaner for Tile & Grout, QT/Brush | Acid-Free, Stain Remover

Amazing product! I used this on the kitchen grout in our new house that was clearly disgusting.. I sprayed, let it sit for a minute and barely had to scrub to lift the grime. It doesn’t smell bad. I worked in sections and wiped with a cloth as I went.. I haven’t mopped yet and there’s minimal streaking on this annoying marble tile. 10/10

I watched one of the review videos on this product and was impressed by how it cleaned the shower grout. I was still skeptical, but ordered it anyway. When it arrived, I immediately use it on the grout on my bathroom floor where I have marble tile. This product did say it was safe for marble. I used it along with the brush that was included. It didn’t take a lot of scrubbing to have the grout immediately look cleaner. This is definitely a good product! I have since used it in my shower, which is also marble tile stone. It took away the rust stains, just as easily as it did the grime stains on the bathroom floor. It’s nice to find a product that actually works and is not all hype!

Removed most of the dirty looking stained grout. A second wash looks clean!

I bought this grout cleaner after reading the reviews and it did not disappoint. It is nice to have on hand to clean heavy traffic spots. It lifts the dirt and looks brand new! So glad I made the purchase!

Expensive. This is better than Scrubbing bubbles in shower or tile floor cleaner that I use periodically and removes most discoloration but not all. Worked better on shower walls than bathroom floor. Does not remove mold. It does require the use of the hard bristle brush. It has a mild odor but not unpleasant. Sprayed on easily. Waited 3-5 minutes, scrubbed and then rinsed with shower water. Sometimes had to use twice to make notable diiference.

This grout cleaner works really well. I sprayed it on, agitated with a grout brush, left it awhile , then mopped. The grout cleaner did its job!

Wow! So easy to use and so effective!! Spray it on, scrub lightly with the included brush, and wipe away 10+ years of accumulated gunk and grime.

I did a test. Half my tile shower floor vs. a home solution of (3:1 paste of baking soda & dish soap, let sit for 5 minutes, then spritz with white vinegar). Both removed the grout stains equally. The best thing about this product was the brush.

Excellent, you have to work with it, that is use an old tooth brush to work out the dirt cos it not magic, you wont be dissatisfied if you do your part.

I bought my house and the floors looked like they hadn't been cleaned since they were originally installed. The before and after are mind blowing!! I didn't mind the smell of the cleaner. It made it smell.. clean. 5 star review Highly recommend this product.

Good product, quick delivery, would recommend

Buenísimo para limpiar las juntas de los azulejos o pisos de cerámica Me parece caro pero es muy bueno

No funcionó en mi cocina, Apliqué, deje actuar por 5min y utilice el cepillo Cepille bastante tiempo y solo cambio muy muy poco. No lo recomiendo por el precio puedes encontrar algo mucho más barato que limpie mejor
