How Long Does It Take For Vinegar To Kill Mold?

If you’ve discovered mold growing in your home, you’re probably looking for a quick and effective way to get rid of it. Vinegar is a common household item that’s often touted as a natural mold killer, but how long does it actually take for vinegar to work its magic?

In most cases, vinegar can kill mold in 1-2 hours. However, it may take up to 24 hours for vinegar to completely kill larger patches of mold and prevent it from returning.

While that brief answer gives you a general idea of vinegar’s mold-busting timeline, there’s a bit more to the story. Keep reading to learn about the factors that impact vinegar’s effectiveness and get some tips for using this natural remedy to banish mold for good.

Factors That Affect How Long Vinegar Takes To Kill Mold

The type of vinegar you use can impact its mold-killing powers. White distilled vinegar is the most effective at killing mold because it contains about 5-8% acetic acid. Apple cider vinegar, which is usually more diluted, may not work as quickly or thoroughly.

The surface you’re treating also plays a role. Non-porous surfaces like tile or glass are easier to clean with vinegar because the mold can’t penetrate deep into the material. Porous surfaces like wood or drywall may require a bit more elbow grease and patience.

How To Use Vinegar To Kill Mold Effectively

To give vinegar the best chance of defeating mold, don’t dilute it with water. Pour white distilled vinegar into a spray bottle and spritz it generously onto the moldy surface. Let it sit for at least an hour, then wipe the area clean with a damp cloth or sponge.

For tougher mold stains, try using a baking soda paste before spraying on vinegar. Mix a few tablespoons of baking soda with just enough water to create a paste, apply it to the moldy area, and let it dry. Spray on vinegar, wait an hour, then scrub the surface with a bristle brush before wiping it clean.

When To Call In Reinforcements For Mold Removal

While vinegar is an excellent natural mold killer, it does have limitations. If you’re dealing with a severe mold problem or mold that covers a large area, vinegar might not cut it. Mold that has penetrated porous surfaces like wood or drywall can also be tricky to eliminate completely.

In these cases, it’s best to call in a professional mold remediation service. They have the tools and expertise to safely remove mold and prevent it from coming back. Plus, they can identify the underlying cause of your mold problem (like a leaky pipe or poor ventilation) and help you fix it to avoid future outbreaks.

Is Vinegar Safe To Use On All Surfaces?

While vinegar is generally safe to use on most surfaces, there are a few exceptions. Vinegar’s acidity can damage natural stone surfaces like marble or granite, so it’s best to avoid using it on these materials. If you’re unsure whether vinegar is safe for a particular surface, test it on a small, inconspicuous area first.

Vinegar is also not recommended for use on certain metals, like aluminum or cast iron, as it can cause discoloration or corrosion. Stick to using vinegar on non-porous surfaces like ceramic tile, glass, or sealed wood for the best results.

Can You Prevent Mold Growth In The First Place?

While knowing how to get rid of mold is important, preventing it from growing in the first place is even better. Mold thrives in damp, humid environments, so one of the best ways to prevent mold growth is to control moisture in your home.

Use a dehumidifier or air conditioner to keep indoor humidity levels below 50%, and make sure your home has proper ventilation, especially in moisture-prone areas like bathrooms and kitchens. Fix any leaks promptly, and consider using mold-resistant products, like moisture-wicking shower curtains or anti-microbial caulk, in areas that are prone to mold growth.

Banish Mold For Good

Now that you know vinegar can effectively kill mold in just a few hours, put this natural remedy to work in your home. Tackle any visible mold growth with vinegar, but also take steps to prevent mold from returning by controlling moisture and promoting proper ventilation. With a little effort and vigilance, you can keep your home mold-free and healthy.
