Does Vinegar Kill Mold? The Truth About This Natural Cleaner
If you’ve ever spotted mold in your home, you’ve probably wondered: Does vinegar kill mold? The short answer is yes! Vinegar is a natural, non-toxic cleaner that can help eliminate mold, but it’s important to know when and how to use it effectively.
How Does Vinegar Kill Mold?
White distilled vinegar contains about 5-8% acetic acid, which creates an environment where most molds struggle to survive. Studies have shown that vinegar can kill about 82% of mold species, making it a helpful tool for tackling minor mold problems at home.
Unlike bleach, which only removes surface mold but does not kill the roots, vinegar penetrates porous surfaces (like drywall, wood, and grout) to help break down mold at its source. However, if mold has deeply infiltrated these surfaces, professional mold remediation is necessary.
When Should You Use Vinegar to Kill Mold?
Vinegar is effective for small, non-porous mold problems, such as:
Bathroom mold on tiles, grout, and shower curtains
Kitchen mold on sinks, countertops, and refrigerator seals
Window sills and frames where condensation leads to mold growth
For larger mold issues (over 5 square feet), mold inside walls, or toxic black mold, vinegar alone won’t be enough. In these cases, a mold remediation specialist is needed.
How to Use Vinegar to Kill Mold
What You’ll Need:
White distilled vinegar (undiluted)
Spray bottle
Scrub brush or sponge
Clean cloths or paper towels
Baking soda (optional for tough mold stains)
Protective gloves and mask
Step 1: Apply Vinegar Directly to the Mold
Pour undiluted white vinegar into a spray bottle (do not dilute with water). Spray directly onto the moldy surface until fully saturated. Let it sit for at least 60 minutes to allow the acetic acid to break down the mold.
Step 2: Scrub the Area
After an hour, use a scrub brush or sponge to remove the mold. For tough mold stains, sprinkle baking soda onto the surface before scrubbing—it acts as a mild abrasive to enhance mold removal.
Step 3: Wipe and Dry Completely
Use a clean cloth or paper towel to wipe away loosened mold and excess moisture. Mold thrives in damp environments, so ensuring the area is completely dry is crucial to prevent regrowth.
Step 4: Prevent Future Mold Growth
To reduce the risk of mold returning:
Reduce humidity levels with a dehumidifier or exhaust fans in humid areas like bathrooms and kitchens.
Fix leaks in plumbing, roofs, and windows to prevent moisture buildup.
Clean regularly with vinegar as a preventative measure, especially in mold-prone areas.
Final Thoughts: Is Vinegar the Best Solution for Mold?
Vinegar is a powerful, eco-friendly option for minor mold problems, but it’s not a cure-all. If you’re dealing with large mold infestations or recurring mold issues, professional help is necessary.
