Steps to Clean Mold from Wood

Step 1: Protect Yourself

Mold can cause health problems, so it’s important to take precautions before starting the cleaning process. Wear protective gloves and a face mask to avoid inhaling mold spores.

Step 2: Remove Loose Mold

Use a soft-bristled brush to remove any loose mold from the wood surface. Be gentle to avoid damaging the wood.

Step 3: Vacuum the Area

Use a vacuum cleaner with a HEPA filter to remove any remaining mold spores. This will help prevent the mold from spreading to other areas.

Step 4: Mix Bleach Solution

Mix a solution of 1 part bleach to 10 parts water in a bucket. This will be used to kill the mold on the wood.

Step 5: Apply Bleach Solution

Using a soft-bristled brush, apply the bleach solution to the moldy area. Be sure to cover the entire affected area.

Step 6: Let the Solution Sit

Allow the bleach solution to sit on the moldy area for 15 minutes. This will give it time to kill the mold.

Step 7: Rinse with Water

After 15 minutes, rinse the area with water and allow it to dry completely.

Step 8: Repeat if Necessary

If the mold is still visible, repeat steps 4-7 until it is completely gone.

Step 9: Use a Fan or Dehumidifier

After cleaning the mold, use a fan or dehumidifier to dry the area completely. This will help prevent the mold from returning.
