As we renovate our 1954 home, finding mold is one of my biggest fears.
I’m someone who often turns to natural cleaning products around my home, but is something like apple cider vinegar enough for removing mold?
Apple cider vinegar does have antimicrobial properties and in some cases, vinegar may help inhibit the growth of mold or even kill it when applied directly to surfaces. However, for severe mold infestations, I would not recommend it as a sufficient solution on its own. Professional mold removal may be necessary.
So, the answer is: Yes, apple cider vinegar can have some effect on certain types of mold, but its effectiveness may vary, and it may not be a comprehensive solution for serious mold issues.
Below, I’ll break down everything you need to know about apple cider vinegar vs mold and mildew, cleaning tips, and more!

Does apple cider vinegar kill mold?
Apple cider vinegar (ACV) is known for its acidic properties, which can be effective against certain types of mold. The acetic acid in vinegar has been shown to have some antimicrobial properties, which can help inhibit the growth of mold and mildew.
However, whether apple cider vinegar can effectively kill mold depends on various factors such as the type of mold, concentration of the vinegar, and the surface on which the mold is present. While apple cider vinegar can be a useful household cleaner and may help in removing some surface mold, it may not be sufficient for more severe mold infestations or deeply embedded mold.
For minor mold problems on surfaces like tiles, countertops, or shower curtains, you can try using undiluted apple cider vinegar in a spray bottle and let it sit for some time before scrubbing the area.
However, if you’re dealing with a more serious mold issue, especially one that extends beyond surface areas or has affected porous materials like drywall or wood, I recommend consulting with a professional mold remediation service. They can assess the extent of the problem and recommend appropriate solutions to ensure effective and safe mold removal.
Also note that while the vinegar may kill the existing mold and prevent it from growing, some stains on materials may not go away, especially if they have been there for a while.
How to use apple cider vinegar for mold
While apple cider vinegar may not be as potent as commercial mold remediation products, it’s often used as a natural alternative for minor mold problems. Its acidic nature can help break down mold and mildew on surfaces like tiles, countertops, and shower curtains.
To use apple cider vinegar for mold removal, follow these steps:
- Pour undiluted apple cider vinegar into a spray bottle.
- Spray the affected area generously with the vinegar solution.
- Allow the vinegar to sit for at least one hour to penetrate the mold.
- Use a scrub brush or sponge to agitate the area and loosen the mold.
- Wipe away the mold and vinegar residue with a damp cloth.
Safety precautions
When using apple cider vinegar for mold removal, it’s essential to take proper safety precautions:
- Wear protective gloves and a mask to prevent skin contact and inhalation of mold spores.
- Ensure adequate ventilation in the area being treated.
- Avoid mixing apple cider vinegar with other cleaning products (especially bleach), as this can produce harmful fumes.
- Test the vinegar solution on a small, inconspicuous area before applying it to larger surfaces. Do not use vinegar on surfaces like marble or any stone material which is more porous.
So, does apple cider vinegar kill mold?
Apple cider vinegar can be a useful natural remedy for minor mold problems in homes and indoor environments. Its acidic properties can help inhibit the growth of mold and mildew on surfaces, providing a safer and eco-friendly alternative to commercial mold cleaners. However, for more severe mold infestations or persistent problems, it’s best to consult with a professional mold remediation specialist for proper assessment and treatment.
FAQs
Apple cider vinegar can start to kill mold upon contact, but the exact time it takes to completely eliminate mold depends on factors such as the severity of the mold infestation, the concentration of vinegar used, and the type of mold. Generally, you may start to see results within a few hours to a few days of consistent application.
Yes, you can use apple cider vinegar instead of white vinegar to combat mold. Both types of vinegar contain acetic acid, which has antimicrobial properties that can help kill mold. However, apple cider vinegar has a slightly different scent compared to white vinegar, so keep that in mind if odor is a concern.
While vinegar can effectively kill mold on surfaces, it may not completely prevent mold from returning, especially if the underlying cause of moisture or humidity is not addressed. Regular cleaning and maintenance, along with proper ventilation and moisture control, are essential for preventing mold regrowth.
Apple cider vinegar is acidic and has antimicrobial properties, which inhibit the growth of mold and bacteria, so it’s highly unlikely. However, if contaminants are introduced into the vinegar, such as by using a dirty utensil or storing it improperly, mold could potentially develop over time. Proper storage in a sealed container and regular inspection can help prevent this.
