Black Diamond Stoneworks Ultimate Grout Cleaner for Tile Floors Blasts Away Years of Dirt and Grime Making Cleaning Easy. Heavy Duty Spray Cleaning Solution. Safe for Colored Grout and Natural Stone

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.

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

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.

Wow! This is the best of the best grout cleaner, zero smell, it cleans grout fast my tile floors never looked so good. I am on my second bottle its worth every penny. It lives up to its name fast action grout cleaner, would highly recommend. It definitely works and my floors and grout are sparkling clean.

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
