Can Apple Cider Vinegar Mold Disappear?

Apple cider vinegar (ACV) is a kitchen staple due to its mild and sweet flavor that enhances a wide range of recipes. It can be used in soups, pickles, salads, sauces, gravies, and even hot drinks. However, beyond its culinary uses, ACV has antibacterial and preservative properties that make it an effective natural cleanser and remedy for various skin and health conditions. Vinegar has been a reliable cleaning solution for centuries, especially for treating wounds, germs, and infections, long before modern chemical cleaners were invented.

So, can ACV kill mold? While ACV has been shown to clean surfaces and walls effectively, can it also be used to kill mold? Let’s delve deeper to discover whether ACV can help solve your mold problem.


Can Apple Cider Vinegar Eliminate Mold?


To understand if apple cider vinegar (ACV) can effectively eliminate mold, it’s crucial to delve into the process of making ACV.

This process involves fermentation of a sugar-containing substance, such as fruits, wine, vegetables, or grains, into acetic acid, a slightly acidic colorless organic compound with a pH of 2.4.

This pH level is capable of killing mold as most species of mold prefer a pH between 4 and 7. Mold spores are sensitive to acidity, and applying ACV to a moldy area can create an environment that is inhospitable to mold growth and multiplication.

Understanding the pH level of ACV is important to decide whether it’s a suitable solution for your mold problem.

pH is a measure of the acidity or alkalinity of a substance. It is measured on a scale from 0 to 14, with 7 being neutral. Substances with a pH below 7 are acidic, while those with a pH above 7 are alkaline or basic.

Mold spores are sensitive to acidity, with most species preferring a pH between 4 and 7. If the pH is outside of this range, it can make it difficult for mold to thrive and multiply. This is where apple cider vinegar comes in.

ACV has a pH level of around 2.4 to 3.5, making it slightly acidic. When applied to a moldy area, it lowers the pH of the environment, making it less hospitable for mold to grow. This change in pH can weaken the cell walls of the mold spores, ultimately killing them.

It’s important to note that while ACV can be effective at killing mold, it may not be the best solution for severe cases. Professional mold remediation may be necessary for extensive mold growth or if the mold is caused by a larger issue such as water damage. Additionally, it’s important to use caution and follow proper safety measures when dealing with mold, as exposure to mold spores can cause health issues for some individuals.


Differences between Apple Cider Vinegar and White Vinegar

After learning about the pH levels of apple cider vinegar and white vinegar, it’s important to note that white vinegar is generally more effective in killing mold than ACV. This is because white vinegar has a higher concentration of acetic acid than ACV, which makes it more acidic.

White vinegar typically contains 5-8% acetic acid and 92-95% water, while ACV contains 5-6% acetic acid and 94-95% water. Although this difference may seem small, it has a significant impact on the pH levels of the vinegars.

White vinegar has a pH range of 2.5 to 2.7, while ACV has a pH range of 3.3 to 3.5. This means that white vinegar is more acidic and therefore more effective in killing mold spores than ACV.

It’s important to note that mold spores are sensitive to acidity and prefer a pH range between 4 and 7. Since white vinegar has a pH below 4, it can easily kill mold spores. On the other hand, ACV is less acidic and therefore has a weaker impact on mold spores.

How Effective is Vinegar as a Mold Remover?


After comparing the properties of white and apple cider vinegar in preventing mold, it’s important to understand that vinegar is not a guaranteed solution against mold.

Studies from Mississippi State University reveal that white distilled vinegar can only kill around 82% of mold species. This percentage may sound high, but it still means that there is an 18% chance that your vinegar solution won’t be able to kill the mold.

Furthermore, vinegar cannot eliminate all mycotoxins that are associated with mold and can lead to various health problems.

It’s essential to keep in mind that vinegar is not a foolproof solution to deal with mold. Even though white vinegar has a decent success rate, the numbers are expected to be worse for apple cider vinegar. ACV has a higher pH and contains less acetic acid than standard vinegar, making it less effective against mold.

Additionally, using apple cider vinegar on certain surfaces can result in stains. The brown color of ACV is unsuitable for surfaces like white walls, carpets, and rugs.

Moreover, ACV contains more sugar than standard vinegar, which can provide more organic food for molds and cause them to multiply even further.

In conclusion, while vinegar can be helpful in dealing with mold, it’s not always the ideal solution. There are limitations to vinegar’s effectiveness, and other methods may be necessary for severe mold infestations.


Effective Ways to Use Apple Cider Vinegar for Mold Removal


If you’re looking to use apple cider vinegar to eliminate mold, here are some guidelines to follow:

First, it’s important not to dilute the vinegar. This will ensure that you’re using as much acetic acid as possible, which is the active ingredient that will have the most impact on mold. So use the vinegar directly from the bottle and apply it to the affected area.

It’s also recommended that you use the ACV solution with the highest percentage of acetic acid that you can find at the grocery store. Most products are 5%, but you may be able to find a 6-7% solution.

Spray an 8-oz glass of vinegar directly on the moldy area, making sure to wet the entire colony. Let the ACV sit for 1-2 hours so that the mold is exposed to the acidic environment for a significant amount of time.

After that, use a sponge or brush to wipe the vinegar off. It’s unnecessary to rinse the area with water, as this may add more moisture and promote future mold growth. Let it air dry and don’t worry about the odor – it will fade away after a short time.

Keep in mind that you may need to repeat this process multiple times for the same moldy area. Apple cider vinegar is not 100% effective against mold and may require more effort to work.

To enhance the effectiveness of the vinegar, you can mix it with a few drops of tea tree oil. This oil has antibacterial properties that can help the ACV kill more spores. Plus, the tea tree oil has a pleasant scent that can mask the vinegar smell.




Despite being mildly acidic, ACV has limitations in terms of mold removal. Recent studies indicate that it can only eliminate around 82% of mold species and cannot eliminate all associated mycotoxins. Additionally, it is not recommended for use on white surfaces or carpets due to its brown color and potent odor. Moreover, ACV’s high sugar content can encourage further mold growth.

In conclusion, if you have mold issues in your property, you can consider using ACV, particularly if you do not have any other alternatives. However, if you have access to standard vinegar or a stronger solution, it is preferable to use those instead. It’s best to reserve ACV for salad dressings rather than for mold removal.
