If you find black mold in your basement, you can remove it with the following steps:
• Get yourself prepped by wearing closed-toe shoes, long sleeves and long pants, gloves, safety goggles, a mask or respirator, and boot covers. You should also open windows and set up fans to improve ventilation, lay down drop cloths to protect the floor, and have contractor bags ready to throw away moldy materials.
• Remove all affected materials including carpeting, curtains, drywall, ceiling tiles, and other fabrics. These materials should be disposed of safely.
• Treat the moldy surface with a mold killing solution. White vinegar is a good option for removing mold growth from tiles and nonporous surfaces. Apply the white vinegar to the surface and let it sit for an hour before scrubbing it with a brush.
• Use a baking soda solution of 2 cups of water and 1 teaspoon of baking soda to remove mold from grout, drywall, and other porous surfaces. Apply the solution with a cloth, rag, or scrub brush.
• For difficult cases, you can use a solution of 1 cup of bleach to 1 gallon of warm water to scrub mold from pipes, tiles, appliances, and other nonporous surfaces. Never mix bleach with vinegar, ammonia, or other household cleaners.
• Use a cloth or a stiff bristled brush to scrub the mold after applying the cleaning solution. You should choose between a cloth or a brush depending on the surface you are scrubbing.
If you do not feel comfortable removing black mold from your basement yourself, call a mold remediation professional.
