Black Diamond Stoneworks Ultimate Grout Cleaner for Tile & Grout, QT/Brush

This is the best grout cleaning product I have found. Still have to scrub with the brush that is included, but at least when you're done the grout it clean.

I can't say enough about this grout cleaner. I have tried several but this one is the best I have ever tried!! I have a large room that has 10" x 10" tiles, off white grout color. The room gets a lot a traffic and the grout has always been difficult to clean. But since I purchase the Ultimate Grout Cleaner I can't believe the difference this has made. Thank you for your product. I will certainly purchase again!

I gave it a 3 cause the instructions are not clear. I applied the grout cleaner to about 4 tile square & waited 3 minutes, scrubbed then wiped. No difference. Did it again waiting 5 minutes. Nothing but I could see the dirt. So I realized if you don’t wipe it as soon as you get done scrubbing the dirt settles back in the grout fast. So spray, wait, scrub & WIPE! I did two bathrooms & a laundry room. It’s been 7 years so it needed it. Looks nice. Not perfect in some spots but happy. Also the sealer comes out of the squirt top like crazy. I put it in a bowl & used a small paint brush to apply. How this helps.

Not all that good!

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!

Love love love this stuff. I was apprehensive about buying it, but I'm glad I did. My old house cleaner ruined my floors by using Dawn soap on my wood tile floors. This stuff it's amazing stuff, I highly recommend. I know in the picture you can't see how bright my floors are but they are.

It is the same floor is just the lighting changed. This is the master bathroom floor, I first swept and washed the floor with dish detergent and water and one of those long brushes you use to wash the car then I spray with the product and while it worked I would spray the rest of the floor, then I used a slim hard brush ( the toothbrush wasn’t hard and sturdy enough) to do the lines, but since my floor has little indentation I scrubbed it all over afterwards with the car wash long brush a lot and in circles, if you only have the grout between the tiles to do, then you are lucky and it will go a lot faster, I then mop the floor several times to take the product off. There is not much smell to it, I am not looking forward to doing the kitchen floor, btw I used almost the whole bottle.

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.

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
