You may remember to clean your refrigerator and stove on a frequent rotation, but other household appliances, such as deep freezers, may miss the regular cleanings. When a freezer isn't cleaned frequently, isn't working properly or a door is left ajar, mildew can grow and invade the freezer. Mildew is a type of mold that can be black or white and is a thin, sometimes fuzzy and smelly growth that thrives in moist conditions. If your chest freezer is a petri dish for mold, pull out some household items to rid the freezer of mildew.
Unplug the freezer. Put on protective eyewear and a respirator mask, such as an N-95, that will not allow you to breathe in mold spores. Remove any remaining food and discard to prevent the spread of mildew elsewhere.
Fill a bucket with 1 gallon of warm water and 1 cup of bleach. Fill a spray bottle with the bleach solution.
Open the lid to the freezer and keep it open while you work. If you are working inside or in an enclosed space, open any windows or doors to ensure proper ventilation.
Spray the sides, lid, bottom, baskets and door gaskets with the bleach solution. Allow the solution to work on the mildew for 15 to 30 minutes, depending on the severity of the mildew infestation. Remember to keep the lid open.
Wipe all the inside surfaces clean of mildew. Use old rags that you can discard in an outdoor garbage can. Once a rag becomes filled with the mildew, discard it and use a clean one. For particularly stubborn mildew, immerse the rag into the bleach solution and scrub until all traces of mildew are gone. Also wipe down the outside surfaces until the freezer gleams.
Dip an old toothbrush in the bleach solution to reach stubborn corners and the ridges in the gaskets and scrub those areas free of the mildew.
Discard the bleach solution and rags.
Rinse the bucket and refill it with a solution of equal parts vinegar and warm water.
Wipe down the inside and outside surfaces and gaskets with the vinegar solution and a clean sponge.
Sprinkle a box of baking soda along the bottom of the freezer. Keep the lid propped open and allow the freezer to dry completely, preferably overnight. The baking soda will help to absorb any remaining unpleasant odors.
Fit the long attachment to the vacuum and vacuum away the baking soda.
