How To Remove Mold From Drywall
Removing mold from drywall can be tricky because if drywall gets too wet, it is ruined. In fact, its often easier to cut out the infected section of drywall and replace it, rather than trying to treat the mold directly. If the drywall feels soft, its beyond saving. However if you do want to clean the drywall without removing it, heres what to do.
Step 1: Brush the mold off the drywall using the scrubbing brush. Try to remove as much as possible without getting the wall wet.
Step 2: Make a 50/50 solution of white vinegar and hydrogen peroxide. Spray it onto the area until it is damp, but not soaked.
Step 3: Wait 10 minutes then use a medium-bristled brush to clean the wall using circular motions. Dont scrub too hard or youll damage the drywall.
Step 4: Wipe down the wall using household disinfectant wipes.
Step 5: Allow the wall to dry. In high-humidity environments, set up a box fan directed toward the wall to dry it as quickly as possible.
If the drywall is stained when dry, use a primer or stain block before repainting. Consider a mold-resistant paint to provide extra protection, and reduce humidity in the room to stop mold from returning.
Cleaning Black Mold With Ammonia
Make an ammonia solution using a ratio of 1 part of ammonia to 1 part of water. Fill a spray bottle with ammonia solution and spray it onto the moldy surfaces. Leave the solution to sit for a number of hours before rinsing with water. After rinsing or wiping with water, allow the areas to dry completely. For vinyl seats like in your boat, combine 1/4 cup of ammonia with 1 cup of water, and pour this solution into a spray bottle. Spray the mold with this mixture, and scrub it with a bristle brush. Rinse the solution off with clean water to remove it from the vinyl seats. If you still notice mold on the seats, use rubbing alcohol.
NOTE Ammonia, similar to bleach kills mold growing on non-porous materials like bathtubs, tiles, countertops, and glass. However ammonia is not an effective killer for mold growing in porous materials like drywall and woods. Ammonia is a harsh chemical, it emits toxic fumes when mixed with bleach. Use ammonia with care.

Killing Mold Using Lemon Juice
If youre concerned about the musty mold smell more than the mold spores themselves, lemon juice would be a good option for you. This natural mold-killer is acidic and leaves behind a pleasant smell that replaces the mildew-like smell of the destroyed mold. Heres a short procedure for eliminating mold on porous surfaces using lemon juice:
- Add some lemon juice into a spray bottle. If youre working on a budget, you can make your own lemon juice at home by blending lemon slices. Otherwise, concentrated lemon juice is always available for purchase at local supermarkets.
- Spray the lemon juice directly onto the mold growth. Due to its acidity, itll quickly kill the mold spores on the porous surface.
- To kill the mold spores that may have already penetrated the porous surface, work the lemon juice into the porous structure using a stiff-bristle brush.
- You should repeat the above steps until you can no longer spot any mold growth. The good thing about lemon juice is that you can combine it with other natural mold-killing products like vinegar for improved results.

Reader Question: Is It Ok To Apply A Sealer Or Wood Preservative Over Black Stains On Plywood Roof Sheathing
Last September I had a new garage roof fitted and within 7 months the plywood used inside developed black mould spots. The company that fitted the roof said it was caused by condensation. Having wiped the roof with a mild detergent I was left with black stains on the plywood. I would like to know if it would be ok to put a wood preservative on it despite the stains – don’t want it to come back.
Would appreciate your advise? –
Yes you can apply a wood preservative, leaving cosmetic black stains under the preservative.
But if you do not find and fix the cause of condensation I’d still expect future trouble. You may find stains or mold appearing on other wood or mold-friendly surfaces in the same area if indoor moisture levels are high, or if there is building insulation present that may become mold contaminated.
