Why Can’t Moldy Drywall Be Cleaned
It is very difficult, usually impossible, to adequately remove mold from porous materials, and that includes drywall. Why? Well, porous materials aren’t entirely solid, even if they appear solid to the naked eye. Materials like drywall have very tiny holes, or pores, in them, much like the pores in your skin. Microscopic mold spores can remain unseen in the pores of the drywall, even when the drywall appears free of mold. It’s similar to the way dirt or oil can be trapped in the pores of your skin, even if you don’t see it.
Much like how dirt or oil trapped unseen in the pores of your skin can lead to acne or other skin problems, unseen mold trapped in the pores of drywall can grow and spread and can also cause health problems. Since there is no effective way to remove mold from the pores of the drywall, the affected drywall must be removed and replaced.

In Addition To Getting Rid Of The Mold You Need To Figure Out Why It Appeared And How To Keep It From Coming Back
Q: How can I clean mold off walls?
A: Your question prompts many more. How much mold are you dealing with? Is it just on the paint or tile, or is it embedded in drywall? Do you have any underlying health issues that warrant extra caution? And do you know why the mold has appeared and what to do to keep it from returning?
Much has been written about serious mold problems and the health consequences. These concerns are valid. But its also important to keep things in perspective. You probably dont need a hazmat team to come in to clean a one-square-foot patch of mold off a wall.
The Environmental Protection Agency suggests about 10 square feet about 3 by 3 feet as a gauge for determining what homeowners can probably clean up themselves with basic safety measures vs. what needs professional-level protocols, whether by the homeowners or by a professional remediation team. This threshold was set because of an understanding of what makes mold and mold cleanup a risky endeavor from a health standpoint. Mold and mold spores are allergenic, and some molds are toxic. This is true whether the mold or the spores are dead or alive, which is why the EPA does not generally recommend using chlorine bleach or other biocides as part of mold cleanup. The chemicals pose their own health risks without a health benefit.
Scrub With Baking Soda Or Borax
Sodium bicarbonate and the natural mineral borax each have a high pH that inhibits the growth and survival of mold. Both products are inexpensive and easy to use.
Make a paste of the powders with a few drops of water and apply it to the areas of mold growth. Let it sit for at least 30 minutes and then use a dampened scrub brush to scour the area. Rinse well with fresh water and dry with an old cloth.
Neither product is as effective at killing mold or removing stains as chlorine bleach or vinegar.
