Image titled Kill Black Mold Step 2Method 2

Mask off the area
  1. To prevent the spores from spreading to other areas of your home during cleanup, the area should be isolated from the rest of the space with 4-6mil plastic sheeting, it is best to maintain a negative pressure in the masked off area so that mold spores cannot migrate to the rest of the living area. Put plastic sheets over the floor and walls directly adjacent to the patch of mold.
    • You should also cover all openings, including doors, windows and vents, with plastic sheets to minimize the amount of mold spores that escape into the air. .

Method 3

Use Personal Protective equipment (PPE)
  1. Protect yourself. Wear a dust mask over your nose and mouth and put on rubber or plastic gloves. It can also irritate the skin and eyes, which is why you should also wear gloves and goggles..
    • For severe cases of black mold, the use of a breathing respirator with HEPA cartridges is recommended over the use of a simple dust mask.
    • Do not use a fan or a home or shop vacuum. The unfiltered air movement produced by these devices can spread mold spores throughout the house.
  2. Rent a HEPA vacuum. Special HEPA vacuums contain filters designed to remove allergens and toxins. You should prepare such a vacuum in advance.

Method 4

Bleach Method
  1. Prepare your chemicals. For surface mold you need to have a bucket filled with a bleach solution and another filled with a general cleaning solution. It is best to use a biocide such as sporicide to kill mold in heavily affected areas. Transfer these solutions to separate spray bottles.
    • Mix 8 oz (250 ml) of bleach with 1 gallon (3.8 L) (4 l) of tap water.
    • Fill another spray bottle with clean, warm water.
  2. Spray the visible mold with your bleach solution. Douse the area from top to bottom.Image titled Kill Black Mold Step 1 Scrub the affected area with paper towels or disposable rags.
    • Do not save or reuse your rags after using them to scrub away black mold. Change the towels you use frequently to avoid spreading spores from the towel back to the surface.
    • Discard your towels by throwing them away in a heavy-duty plastic garbage bag.
  3. Clean the area with bleach. Spray the affected surface with your diluted bleach solution and let it sit for 15 minutes before wiping it away.
    • Commercial fungicides formulated to treat mold can also be used in place of, or in addition to bleach. Use the fungicide after cleaning the area and follow the instructions on the label when applying it.
  4. Vacuum the area. After the surface dries, use a HEPA vacuum to clean the off dead mold and spore bodies.
    • Vacuum for at least one minute per 1 square ft (930 square cm) of affected area.
    • Dispose of the vacuum filters in a heavy-duty plastic garbage bag. Throw out the garbage bag as you would throw out normal household garbage.
  5. Image titled Kill Black Mold Step 4Clean up. Flush any waste water down the toilet, utility sink, or floor drain. Wash your clothes after you finish cleaning up the mold.
  6. Coat the affected area with borax. Mix 1 cup (250 ml) borax with 1 gallon (3.8 L) (4 l) hot water. When fully dissolved, transfer the borax solution to a spray bottle and spray it onto the moldy area. After a few minutes pass, scrub the mold away with a scrubbing brush.
    • Do not rinse the borax away afterward.
    • Create a borax paste using less water. This paste can be applied to the moldy area and allowed to sit for several minutes. Scrub the paste and mold away with a scrubbing brush.
    • Borax is a natural, white mineral powder. It is used as a fungicide, as well as a pesticide, herbicide, disinfectant, and deodorizer.

Method 5

Natural Remedies
  1. Use tea tree oil. Mix 2 tsp (10 ml) tea tree oil with 2 cups (500 ml) water in a spray bottle, shaking vigorously to combine. Spray the solution on affected areas.
    • Do not rinse the solution off. Allow it to soak into the mold and reapply it if necessary.Image titled Kill Black Mold Step 5 You may dab it into the contaminated area though.
    • This solution can be stored indefinitely.
    • Tea tree oil can be expensive and it has a potent odor, but the smell should dissipate within a couple of days.
  2. Try grapefruit seed extract. Combine 20 drops of grapefruit seed extract with 2 cups (500 ml) of water in a spray bottle. Shake to mix and douse the contaminate area with it.
    • Do not rinse the solution off the surface. You can dab it into the area with a dry paper towel, but you should not rinse or wipe it away with water.
    • Like tea tree oil, grapefruit seed extract lasts indefinitely and is expensive. Unlike tea tree oil, however, it is odorless.
  3. Apply vinegar. Pour straight, undiluted vinegar into a spray bottle and spray the vinegar directly onto the black mold. Let it set without rinsing or scrubbing.
    • White distilled vinegar can kill 82 percent of mold. Since black mold is so resilient, it is best to use vinegar without diluting it.
    • The strong odor should fade within a few hours.
  4. Remove mold with baking soda. Mix 1 tsp (5 ml) baking soda with 2 cups (500 ml) water in a spray bottle, shaking rapidly to blend the two together. Spray the black mold with the solution and scrub it with a scrubbing brush. Rinse with clean, warm water.
    • After rinsing the solution away, spray the area with the baking soda solution again and let it dry naturally. This will help kill remaining mold.
    • You can also use baking soda in conjunction with vinegar. Use one after the other. It is generally thought that the mold not killed by the vinegar can be killed by the baking soda.
  5. Make a hydrogen peroxide solution. Pour 3 percent hydrogen peroxide directly on the black mold. Wipe it clean when done.
    • Hydrogen peroxide can be harsh, so it is best to avoid letting it sit on the affected area.
  6. Coat the affected area with borax. Mix 1 cup (250 ml) borax with 1 gallon (3.8 L) (4 l) hot water. After it fully dissolves, pour the borax solution into a spray bottle and spray it onto the moldy area. Let it work for a few minutes, scrub the mold away with a scrubbing brush.
