To remove mold from your home, thoroughly inspect the surrounding areas to identify the cause of the mold, and neutralize it to prevent future growths. Check for poor air circulation and sources of moisture, as these are the conditions necessary for mold growth.
If the mold appears on painted or primed drywall, simply wipe or scrub the mold away using a cleaning or mold-killing solution to completely remove the mold. If the mold appears on unpainted drywall, use a utility knife to remove the affected portion of the drywall, put a new section of drywall in the region you cut out, and apply joint compound on the section. Let the area dry for at least 24 hours, and use sandpaper to smooth the surface. Use a HEPA vacuum to clean the room to remove mold that may have stirred during the process.
To remove mold from a wooden surface, wipe or scrub the surface using a sponge, cloth or scrubbing brush, along with a household cleaner such as detergent. If a mold stain remains, try cleaning it out using bleach. Since there may be mold spores left over, use a HEPA vacuum to clean the wooden surface. Then, coat the surface with paint or a fungicidal sealant.
