What I Use

Here’s a list of everything I use to Clean Marble Shower Tile or Marble Bathroom Tile.

Watch this short video for a quick walk through of How to Clean Marble Shower Tile weekly, safely kill mildew, and how to seal your marble in a shower.

How to Clean Marble Shower Tiles Daily & Weekly

About once a week, I squirt about a tablespoon of Dawn Dish Soap into a plastic container before heading into the shower. You can use other Dish Soap’s, just make sure they say they are “soft” or PH neutral AND that they don’t contain extra ingredients like skin moisturizers, scents, etc.

Once I’m in the shower, I add water to the dish soap in the container and use an old soft-bristled toothbrush and a soft cloth to scrub the tile and grout clean. You should avoid using any rough or abrasive scrubbers on marble tile.

How to Clean Marble Tiles and Get Rid of Mildew and Mold.
Make sure to clean that soap and shampoo build up on marble tile to prevent mildew and mold growth.

Marble tile is porous, and kinda soft (for a stone). It can be scratched by hard scrub brushes and cleaning pads. I’ve been using a non-abrasive 3M Scrub Dots wash cloth with little plastic dots on one side as a way to scrub away shampoo and soap residue in the grout. They also make a Scrub Dots Sponge you can see here.

AND, I try to dry off the tiles every time I use the shower. This just helps prevent mildew growth and hard water stain build up. Although, I have to admit, my husband doesn’t do this. But, try to do it as often as you can. 🙂

How to Clean Marble Shower Mold & Mildew

OK, now you know how to clean marble shower tile weekly, but there’s one more easy step to prevent or stop mold and mildew growth. And, this really couldn’t be simpler. Once every 3 to 5 weeks, I spray on Marblelife Mold and Mildew Stain Remover. You want to make sure all of the grout is wet with this mildew remover.

Then let that soak in and work for 5 minutes before washing it all off with water. This has a strong smell, so run the fan to get rid of those fumes. You can see the before and after of the mildew on my tile in that How to Clean Marble Shower Tile video above.

Here’s a look at the mildew that I let build up on my shower floor before making this how to video. Yuck!

How to Seal Marble Tile

Sealing the marble tile is pretty easy too. Marble should be sealed once a year, unless it’s in a high traffic area. I consider a shower a pretty high traffic area. How about you? So, I seal my shower tile about every 6 months. You’ll know when it needs to be sealed. It will darken when it gets wet because it’s absorbing water.

Seal a clean dry shower by spraying Black Diamond Granite Sealer onto a clean rag, then wipe it into the tile in a circular motion. Keep spraying the sealer and wiping on until you’ve finished all of the tile. You don’t need to saturate the tile with the sealer, but it should look slightly wet across the whole tile.
