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)

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!

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 saw this advertised and decided to check it out. Just spray, let sit a few minutes and scrub with the brush. It works in seconds. Its so easy to use. Just spray on the grout, wait a couple minutes and scrub. Years of stain came off. It has a pleasant smell. The mist spray makes it go where you want it. I no longer dread cleaning the grout.

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.
