What is the recommended method to remove mold from wood framing members?

1. Dry brushing

2. HEPA damp wiping

3. Pressure washing

4. Using bleach solutions

The correct answer is: HEPA damp wiping

The recommended method to remove mold from wood framing members is HEPA damp wiping. This technique involves using a damp cloth or sponge, combined with a HEPA vacuum, to capture mold spores effectively while minimizing the release of airborne particles. The moisture from the damp material helps to keep mold spores from becoming airborne during the cleaning process, ensuring a more thorough and safer remediation. Using a HEPA vacuum additionally ensures that the fine particles that might not be picked up by a regular vacuum are captured, thus providing an added layer of effectiveness. This approach is crucial because wood is a porous material that can harbor mold, and damp wiping allows for effective removal without damaging the wood itself. The other methods tend to be less suitable for mold removal from wood. Dry brushing may disturb mold spores without capturing them, potentially spreading them into the air. Pressure washing can lead to further damage of the wood and may drive moisture deeper, exacerbating the mold problem. Using bleach solutions is ineffective on porous materials like wood, as bleach does not penetrate the surface and may leave behind moisture that can encourage mold regrowth.
