Black Diamond Ultimate Grout Cleaner: Best Cleaner for Tile,Ceramic,Porcelain, Marble Acid-Free Safe Deep Cleaner & Stain Remover for Even The Dirtiest Grout. (1-Quart/1-Brush)

Great product. You can clean the grout with no effort

Works like magic! The grout is mostly back to white again and it was easy to use.

The product itself works okay, not perfect but adequate with scrubbing. The biggest issue I had is the bottle coming unscrewed while using the product and then falling and making a mess all over.

This treatment really works and I m glad that I found it here. I have tried other brands, but no success. The cost is reasonable and I like the brush that comes with the cleaner. I will recommend it to my friends and will buy it again for sure.

Worked very well with minimal scrubbing. My grout hasn't been cleaned since I moved in. I sprayed this let it soak for 5 mins then sprayed a Clorox all purpose and it came right off. I did the process twice because of all the build up Before and after

Get the one with the stiff bristle brush. It’s literally as easy as spaying on and using the brush to loosen the dirt and it brings you grout back to pretty much new! You don’t need gloves or glasses as it doesn’t have acid. I wish I knew about this sooner!! I have labored for hours cleaning grout and now it takes a 10th the time and looks better than any other product I’ve ever used!! Super easy clean up too!

I did not find success with this stain removal. Looked good for a day or two and then look exactly the same prior to trying cleaner. Would not recommend.

I had high hopes for Blue Diamond Grout Cleaner, mainly because it doesn’t have the overpowering smell that most grout cleaners do—that’s definitely a plus. Unfortunately, it didn’t perform the way I expected. I applied a generous amount to my ceramic tile and let it sit much longer than recommended (2–3 hours instead of a few minutes), and even repeated the process. Despite a lot of scrubbing, I only saw a very slight improvement. I even tried adding Dawn dish detergent to boost the cleaning power, which helped a little more, but still not enough to make a real difference. Overall, it performs about the same as many other products that claim to be “the best.” I wasn’t impressed. Put It to the Test (Even With Steam)—Still Falls Short

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

I have tried a lot of grout cleaners. Truthfully this is the most effective one I have found. You won't be disappointed. Albeit you are still on your hands and knees with a scrubbing brush, but you can actually see the dirt start to bubble up. You will need to wipe down each area where you apply the cleaner, but I would suggest that if you have a floor steamer, use this rather than just washing the floor with your usual cleaner.

It is so easy to use. You spray it on and 2 to 5 minutes later, scrub it with scrub brush, then rinse it. Good as new.

très bon produit je le recommande
