Marblelife Maxout Deep Grout Cleaner, Powerful Tile and Floor Cleaning Liquid, Ready to Use, 32oz

For 15 years I have been cleaning my tile floors with an electric floor scrubber. Though it cleans the tiles, it doesn't clean the grout. I have bought and tried many "grout cleaners" that did not work. This stuff - WOW! It pulls the dirt right out! I used a battery operated scrubber from Amazon, so I didn't need to kneel down to scrub. If your grout is really dirty like mine, it will take time and effort. Cleaning up the dirty suds on your tile will take some doing. I used my Hoover Floormate to get what I could, then wound up Swiffering. It is still a work in progress, but well worth doing.

THIS PRODUCT CLEANS GROUT ON MARBLE FLOOR VERY WELL. YOU WILL NEED TO USE A NYLON BRUSH ON YOUR DARKEST GROUT LINE AND SCRUB IT A LITTLE. THIS IS A GREAT PRODUCT.

This product does work but do do you. The grout did come out cleaner but not as sparkling white as desired. No fumes or caustic chemicals. I used the scrub brush and followed directions exactly. Next time I will leave product on longer than the directions

Took the shine of a newly polished marble floor - crema marfil. I only used this product along the edges where the floor meets the baseboard but the product has taken the shine off the marble.

First image is the same room of floor not cleaned. Second is cleaned and washed. Same room, different section. I have 1/2 inch solid marble and it worked just as instructed! I used a kitchen brush and scrubbed it. Let it sit for 15 minutes and then washed it with a norwex towel of just water. It looks like new. I have a lot of floor left to do, and it will take more solution, it doesn’t go super far. Definitely worth it! Marble not harmed, it actually looks better and no residue.

DID NOT WHITEN MY SHOWER FLOOR TILES AS I WANTED.

I used this product to remove the long time grout on my tile floor. This product work great!!! I had tried many different grout cleaner products, but only this one can clean out the old grout from my tile floor. Although this product is a little pricy, but it worth the money. I will buy again in the future.

We had a renovation done at our home during the winter and had workers with dirty shoes and various building materials in and out of our front landing for several months. Those floors got very dirty and stained and the grout was the worst. The Marblelife Maxout did a great job when left on for a few minutes and scrubbed with a strong grout brush.
