Marble Life 0708 MaxOut Tile & Grout Cleaner

I have a new marble shower. The water doesn't all run into the drain so the always seems to be some water on the floor. My floor seems to turn pink and moldy quickly. I do have to scrub well around each little piece of tile but in the end, it gets MOST of it out. Not perfect but works well enough that I'll keep buying it.

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.

We have well water. Despite a water softener, our grout turn orange after some time. I am limited to the cleaners I can use because our tiled shower floor is marble. I've been using a competitor's cleaner (Stone-eez by Clean-eez) and that works, albeit with a ton of elbow grease.Maxout did not budge the discoloration. I followed the directions and scrubbed, a lot. Note: this is not a concentrate. I had to use an entire bottle to do the walls and floor of our 5ftx5ft shower. Stone-eez is concentrated, so you can adjust the strength accordingly. Much more economical.Maxout might work on other kinds of dirty grout. Not iron-colored stains.

Works exceptionally well when the grey grout around my marble begins to turn a peachy pink color (it’s a common bacterial growth called Serratia marcescens that occurs in bathrooms due to the humidity).The only reason I removed a star is because this cleaner is quite expensive. I will be looking for another product that works as well for a lower price.

This s the only thing that will get my grout clean on my shower floor. I have herringbone marble tile so there are a lot of grout lines. I put it in a spray bottle and let it sit for about 15 minutes before I start scrubbing. I wish they would make a spray bottle version. Highly recommend!
