5 Ways to Clean Mold Off Natural Stone Shower

Mold Off Natural Stone Shower

Walls in your shower are usually made of natural stone or tile, which can be prone to mold growth over time when they're not properly cleaned. Here are five ways to clean mold off natural stone shower walls and keep them mold-free so you can enjoy your morning shower again!

Different types of mold

There are many different types of mold that can grow on natural stone shower surfaces. The most common type of mold is black mold, which can be identified by its black or greenish-black color. Other types of mold include white mold, pink mold, and blue mold. Each type of mold has different characteristics and requires different cleaning methods. For example, if you have black mold, then you should use a bleach solution to remove it, while pink and blue molds require vinegar or hydrogen peroxide solutions.

Use bleach and water solution

For a bleach and water solution, mix one cup of bleach with one gallon of water. Fill a spray bottle with the mixture and liberally apply it to the moldy areas. Let it sit for about 30 minutes before scrubbing with a brush. Rinse the area well with clean water and let it air dry.

Use vinegar solution

Vinegar is a mild acid that can safely be used on natural stone. Make a solution of one part vinegar to three parts water, and use it to clean the moldy areas of your shower. Apply the solution with a sponge or cloth, scrubbing gently until the mold comes off. Rinse the area well with clean water afterward.

Use baking soda/baking powder and water solution

Baking soda or baking powder can be used to clean mold off natural stone showers. Make a paste of baking soda or baking powder and water, and apply it to the moldy areas. Let it sit for 30 minutes, then scrub with a brush. Rinse with water and dry the area. If stubborn stains remain, use hydrogen peroxide: Mix one part hydrogen peroxide to two parts water. Apply liberally on the stained area. Let it sit for 15-20 minutes before scrubbing with a sponge or cloth. Repeat if necessary; rinse thoroughly and let dry.

Mildew is caused by excess moisture in the air, so ensure you keep your shower well ventilated by using exhaust fans when taking showers and running hot showers at least five minutes before entering them to remove excess moisture from the air as much as possible.

Use a Professional Cleaner

If you have natural stone in your shower, keeping it clean and free of mold is important. The best way to do this is to use a professional cleaner that is specifically designed for natural stone. MB-9 Mold & Mildew Remover is a great option. Simply spray it on and let it sit for a few minutes before wiping it away. You'll be amazed at how well it works!


Mold can be tough to clean off natural stone showers, but with the right tools and a little elbow grease, it can be done.
