To kill mold on wood effectively, follow these steps and methods:
Cleaning Solutions and Methods
- Bleach Solution : Use a mixture of 1 part bleach to 10 parts water. Apply with a bristle brush or sponge to scrub the moldy wood surface. This kills mold but may not prevent regrowth
- White Vinegar : Spray undiluted white vinegar on the moldy area and let it sit for about an hour before scrubbing and wiping clean. Vinegar is a natural acid that kills mold spores effectively
- Hydrogen Peroxide : Apply a hydrogen peroxide solution to the mold, let it sit for 10 minutes, then scrub and rinse. It can require multiple treatments for stubborn mold
- Baking Soda : Mix 1/4 cup baking soda with 1 quart of warm water in a spray bottle. Spray the wood, let it sit 15 minutes to an hour, scrub with a brush, wipe clean, and reapply. Baking soda kills mold and deodorizes
- Borax : Mix 1 cup borax with 1 gallon hot water. Apply with a brush, scrub, wipe residue, and let dry. Borax also prevents future mold growth
- Dish Detergent and Water : For mild cases, a solution of dish detergent and water can clean mold without harsh chemicals. Scrub gently to avoid damaging wood finish
Additional Tips
- Ventilate the Area : Open windows and doors to allow airflow and reduce moisture
- Avoid Saturating the Wood : Excess moisture can worsen mold problems, so use cleaning solutions sparingly and dry wood thoroughly afterward
- Sanding : For mold stains embedded in wood, sanding the surface may help remove visible mold and stains before cleaning
- Prevent Recurrence : After cleaning, keep wood dry and well-ventilated to prevent mold from returning
- Safety Precautions : Wear gloves, a mask, and eye protection when cleaning mold to avoid exposure to spores
When to Call Professionals
For extensive black mold infestations or mold inside wood that compromises structural integrity, professional mold remediation is recommended. Experts can safely remove mold, assess hidden infestations, and address moisture sources to prevent recurrence
. In summary, killing mold on wood involves applying mold-killing solutions like diluted bleach, white vinegar, hydrogen peroxide, baking soda, or borax, scrubbing gently, and ensuring the wood dries completely. For severe cases, professional help is advised to ensure thorough and safe mold removal.
