Tips

  • If you can't find the source of mold growth, consult a professional, especially for areas over 10 square feet.
  • Always use personal protective equipment (PPE).

Common Mistakes to Avoid

1. Using only water to clean moldy wood

Reason: Water alone won't kill mold spores; it might spread them and make the problem worse.
Solution: Always use a mold-killing solution, like a mixture of bleach and water or a commercial mold remover, in addition to scrubbing with water.

2. Not addressing the source of moisture

Reason: Mold thrives on moisture. If the source of the moisture isn't fixed, the mold will likely return.
Solution: Identify and repair any leaks or sources of excess humidity before cleaning and treating the mold.

FAQs

Can I use bleach to kill mold on wood?
While bleach can kill mold, it can also damage and discolor wood, especially if it's a softwood or if the bleach isn't properly diluted. It's generally recommended to use a solution of water and mild detergent first. If the mold persists after thorough cleaning, consider using a mold-specific cleaner following the product instructions carefully. Always test any cleaning solution on an inconspicuous area first.
