How do you get rid of mildew inside walls?

Answer 1

Mildew is caused by lack of airflow and moisture in the air. You can get rid of it by using bleach, but that won't deal with the underlying cause. You have to change the environment. Open the windows or get an extractor system if you can. Make sure that the area outside of the window is clean and dry. If the window is low, make sure than there is drainage so that water does not bounce up into the window frame. Replace caulking as needed.

Get a small spray bottle and fill it 2/3 full of water and 1/3 full of bleach. Spray it on the mildew and let it set in. Wipe it off with a wet rag and repeat until it disappears. This method also works on bathroom walls where mildew and mold like to accumulate over and near the shower.

Answer 2

You can remove mildew from the exterior of a house by just using some bleach and water. This will also remove any smell left from the mildew. Make sure to use a power sprayer to remove chemicals when finish.

Answer 3

If you have mold and mildew in the walls, you most likely have a leak or other issue with water coming into the home. Besides replacing the drywall, you will need to get that fixed. Some people have recommended hiring a professional to evaluate the extent of the mold damage. When storing materials, packing such buffers as silica gel with the goods before sealing the container will help keep excess moisture at bay.

For basements, sprinkle chlorinated lime (commonly called chloride of lime or bleaching powder) over the floor. Let it sit until musty mildew odors disappear. Then sweep it up. Increasing the heat and air circulation into the basement will help this process. Get rid of mildew on tiled walls and bathrooms floors by scrubbing them with a diluted solution of sodium hypochlorite or chlorine bleach, 1 cup of bleach to a gallon of water. Rinse with clean water and wipe as dry as possible. Keep the windows and shower curtain open until the walls and floors are thoroughly dry.

Mildew on the north side of a house is inevitable. For an easy clean, mix JoMax (found at Home Depot or Lowes) and bleach in a handheld or backpack sprayer. Spray the affected area, let it sit for 5 minutes, then wash off with a hose. Repeat this process if necessary.

I've used this mixture for years on surfaces ranging from metal fences to vinyl siding, and have had great results on both. Make sure to wear eye protection, and I wouldn't recommend spraying that concoction on a windy day.
