Expert Recommendations for Treating Mold on Wood

Dr. Emily Carter (Environmental Microbiologist, GreenClean Solutions). “To effectively combat mold on wood, a solution of one part bleach to ten parts water is highly recommended. This mixture not only kills existing mold spores but also helps to prevent future growth if applied correctly and allowed to dry thoroughly.”

James Thompson (Restoration Specialist, SafeHome Restoration). “I advise using a commercial mold remover that contains fungicides specifically designed for wood surfaces. These products penetrate the wood fibers and eliminate mold at the root, ensuring a more permanent solution compared to household remedies.”

Linda Martinez (Home Improvement Expert, DIY Home Magazine). “For a more natural approach, a mixture of white vinegar and water can be sprayed on the affected area. Vinegar is a mild acid that can kill about 82% of mold species. It is crucial to allow the vinegar to sit for at least an hour before wiping it off to maximize its effectiveness.”
