Does Vinegar Kill Mold and Mildew?
Vinegar kills mold and mildew without introducing the artificial chemicals that comprise household cleansers. The acetic acid inside vinegar is fatal for just about all plants with which it comes in contact, so putting white vinegar into a spray bottle is the first step in combating mold or mildew.
Once the vinegar is in the spray bottle, the next step is spraying the areas in the home, office or other space affected by mold or mildew. The vinegar should set on the mold or mildew for several minutes, and then wipe away the entire mess to get rid of the problem.
