- 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](https://homesteady.com/facts-5073620-mildew.html) 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.
