Pour 1 cup household bleach into a bucket with 1 gallon warm water. Stir the solution to mix.
Wear rubber gloves to protect the skin on your hands and arms from getting dried out from the bleach.
Soak a clean cloth in the bleach solution, then squeeze out the excess liquid. Wash down your walls where mildew odor exists. The diluted bleach will kill any existing mildew spores while removing the accompanying odor.
Allow your walls to air-dry. Open windows, when possible, to circulate fresh air in order to aid the drying process and remove strong bleach smell.
Remove lingering mildew odor on your walls with white vinegar poured onto a clean cloth. Wipe the smelly surface with the vinegar-soaked cloth, then let it air-dry.
