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

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 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

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!

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
