Does Vinegar Kill Mold? A Detailed Answer

Updated: Sep 26

Ever wondered if vinegar can get rid of mold? this is the answer for you


Mold is an unwelcome guest in any home. Not only does it look unsightly, but it can also pose health risks, including respiratory issues and allergies. When faced with a mold problem, many people search for effective and safe solutions to eliminate it. One commonly asked question is, "Does vinegar kill mold?" The answer is yes, vinegar is a mild acid that

can effectively kill mold.


Why Vinegar Works Against Mold?


Vinegar contains acetic acid, which has been shown to kill approximately 82% of mold species. It's a natural and non-toxic alternative to harsh cleaning chemicals, making it a popular choice for those looking to maintain a chemical-free home environment.

What Vinegar Should I Use?


Not all vinegars are created equal when it comes to mold-killing properties. Cleaning vinegar, which typically contains 6% acetic acid, is the most effective type for killing mold. However, regular white vinegar with 5% acidity can also work well. If you don’t already have vinegar at home, it can be easily and inexpensively purchased at most grocery stores.


How To Use Vinegar to Kill Mold?


Vinegar can be used to combat mold on both nonporous and porous surfaces. Unlike bleach, which may struggle to penetrate porous materials like wood, vinegar can effectively reach and kill mold growing underneath the surface.

Here’s a simple step-by-step guide on how to use vinegar to kill mold:

  • Apply Vinegar: Fill a spray bottle with vinegar and generously spray the moldy surface.

  • Let It Sit: Allow the vinegar to sit on the moldy surface for at least one hour. This gives the acetic acid time to penetrate and kill the mold.

  • Scrub Off Mold: After letting the vinegar sit, use a scrubbing brush or sponge to remove the mold from the surface.

  • Wipe Clean and Dry: Finally, wipe the surface clean with a damp cloth and allow it to dry completely.
