How To Clean A Marble Tile Shower
Here’s a quick overview of the steps I use to clean marble tile showers. Keep reading after this list for more details and tips to help you clean marble shower grout and tile.
- Scrub the shower walls and floor once or twice a week with a Dish Wand filled with Dawn dish soap. Or, you can use a similar dish soap that doesn’t have moisturizers or citric acid in it’s mix.
- Once every 3 weeks, spray the entire marble tile shower with a mold and mildew removing spray that is MADE FOR stone and marble tile grout. I like this Stonetech Spray.
- Once or twice a year, you can whiten shower grout with normal grocery store hydrogen peroxide. For a stronger whitener, you can lightly scrub and apply an OxiClean paste to the grout. (See video)
- Once a year, you should seal your marble tile. I like this easy to use Black Diamond spray sealer.
How To Remove Mold And Mildew On Marble Shower Grout
I use Dawn Dish Soap in a Scrubbing Wand once or twice a week to clean marble shower tile and grout. Dawn is pretty great for removing soap scum, shampoo build up & all the other random dirt and grime.
But, Dawn doesn’t really have any built in mold and mildew remover. So, every few weeks, after cleaning my tile and grout with Dawn, I spray on a Mold and Mildew Remover that’s safe on marble and other stone.
Make sure you get that spray across all of the grout and tile. If it’s easier you can spray on a bunch, then use a clean rag to spread it evenly across the walls and floors. Don’t forget to wear gloves.
The grout in the corners of the shower and all along the edges seem to get that icky pink shower mold first, so give them a little extra spray.
Be sure to follow the directions on the container to get the best results.
How To Whiten Shower Grout (Safe On Marble And Stone)
To whiten shower grout, I like to use hydrogen peroxide or an OxiClean whitening paste. Both os those options are safe on marble shower grout and tile. I explain how to use each below.
Be sure to start with clean tiles and grout. I went over how to clean grout between marble tiles in the sections above.
Just in case you’re wondering, dingy looking grout doesn’t mean that it’s dirty. Grout just slowly accumulates stains the same way that teeth stain from things like coffee, tea, and wine.
Hydrogen Peroxide
When the stains aren’t too bad, you can whiten shower grout with the hydrogen peroxide that you find at your local pharmacy or grocery store.
To keep the hydrogen peroxide in contact with the grout for as long as possible, I line the shower floor with paper towels. Then I saturate those paper towels. I usually leave that overnight.
You can spray the walls directly. Generally, the walls aren’t as dingy as the floors. But if they are, you can try to stick saturated paper towels to the wall too.
OxiClean White Revive
If the grout is extra dingy, OxiClean has a higher concentration of hydrogen peroxide. So, it whitens even better.
I run the shower to get the shower floor wet. Then I sprinkle on the OxiClean White Revive. You want enough to create a thin layer of paste in all of your grout lines.
Add water and OxiClean as needed. Use a non-scratch scrub brush or rag to mix that water and OxiClean into a paste. Then spread that into the cracks. I let that sit for half an hour before rinsing it away.
Wear a glove with this option, that OxiClean isn’t toxic but it can irritate your skin.

How To Remove Hard Water Stains On Marble Tile
Some hard water removes aren’t safe for marble and stone tile. So, I usually use a non-scratch Scotch-Brite scouring pad to scrub any hard water stains off of my marble.
If you have a lot of hard water stains to remove, try Stone Pro’s Stone and Glass Scrub. It’s safe to use on marble and glass shower doors.
