MB-9 Mold & Mildew

Mold and mildew are fungi that grow in areas where there is moisture. Your stone surfaces can also fall prey to the growth of these harmful organisms. Because marble and other surfaces can be cleaned at home using a mold and mildew cleaner, you can apply the product for instant mold and mildew removal. Our MB-9 Mold and Mildew product comes in a spray bottle for your convenience to help you apply the chemical in hard-to-reach areas and rid your home of harmful mold.

The truth is that mold and mildew can also form within the stone. MB-9 is designed to treat mold and mildew that forms on the surface, so if you notice a more serious issue deep within the stone, you will need to consult a stone restoration professional. Contact Us to find one near you!

In areas of the home where dampness can be found, mold and mildew often grow. These fungi produce spores that can cause various health issues, drastically reducing air quality. According to the CDC, the health implications of mold are diverse. Mold may make some people feel congested, have a sore throat, cough or wheeze, have burning eyes, or develop a skin rash.





Individuals who suffer from asthma or mold allergies may experience more severe reactions. Moreover, mold infections can cause respiratory problems in those with impaired immune systems and chronic lung diseases.


Removing mold from your home is of utmost importance! Allowing mold to fester will worsen the symptoms you experience and could cause lasting damage to surfaces around the home. Moreover, the CDC recommends using mold removers on hard surfaces as an effective remedy.

MB-9 Mold and Mildew cleaner is safe to use on natural stone. We recommend ensuring you have access to ventilation, especially if you are sensitive to the fumes. Rinse the area thoroughly after use. If using on natural stone, use a soft microfiber towel or brush for agitation if needed.

When applying the solution, you may get some of it on your clothing. To remove it, simply remove your clothes as quickly as you can and wash them thoroughly before reuse. You can find more information in the SDS. You can find the SDS in the "More Information" tab above.

MB-9 does not prevent mold growth from happening. This product is designed to be an instant mold and mildew cleaner, so you must use it every time you notice mold growth. We recommend wiping down your shower after use to clean up any residual moisture to prevent mold growth, especially if there is a lack of ventilation in your shower or an area prone to mold and mildew growth.
