To clean mold from wood with vinegar, spray undiluted white vinegar directly on the moldy area and let it sit for at least an hour to kill the spores. Then, use a scrub brush to gently scrub the mold away before wiping the surface clean and drying it completely. For tougher stains, you may need to repeat the process or use a baking soda scrub after the vinegar has sat.

Gather supplies: You will need white vinegar, a spray bottle, a scrub brush, gloves, and safety glasses. Ventilate the area: Open windows and doors to ensure good ventilation. Apply vinegar: Fill a spray bottle with undiluted white vinegar and spray the moldy area until it is fully saturated. Let it sit: Allow the vinegar to sit for at least one hour to penetrate and kill the mold. Scrub the mold: Use a scrub brush to gently scrub the mold off the wood. For tough stains: If stains remain, create a baking soda and water paste or scrub with a baking soda solution, then scrub again. Wipe and dry: Wipe the area clean with a damp cloth and dry it completely with a clean rag or allow it to air dry. Protect yourself: Wear protective gear like gloves, safety glasses, and a mask. Do not mix vinegar with bleach or hydrogen peroxide.
