If you’ve discovered mold growing in your home, you might be wondering what to do about it. Vinegar is a common household item that can be effective at killing mold, but how long should you let it sit on the mold for maximum effectiveness?
For best results, let the vinegar sit on the moldy surface for at least 60 minutes. This will give the acetic acid in the vinegar time to penetrate the mold and kill it completely.
While letting vinegar sit for an hour is a good rule of thumb, there are some nuances to keep in mind depending on the severity of the mold problem. Keep reading to learn more about how to tailor your vinegar mold removal strategy for best results.
How To Use Vinegar To Clean Mold: Step By Step
Using vinegar to clean mold is a simple process. First, fill a spray bottle with undiluted white vinegar. Then, spray the vinegar directly onto the moldy surface, making sure to fully saturate it. Let the vinegar sit for at least an hour, then use a scrub brush or sponge to remove any remaining mold and stains. Finally, wipe the area down with a damp cloth to remove any leftover vinegar smell.
For tougher mold stains, you may need to repeat this process a few times. You can also try letting the vinegar sit for longer – up to overnight – before scrubbing. Just be sure to keep the area well-ventilated while the vinegar is working its magic.
Is Vinegar As Effective As Bleach For Killing Mold?
Many people wonder if natural cleaners like vinegar are as effective as harsher chemicals like bleach when it comes to killing mold. The good news is that vinegar can be just as effective as bleach, without the harsh fumes and potential health risks.
In fact, some studies have shown that vinegar is actually more effective than bleach at penetrating porous surfaces like wood and drywall, where mold often grows. Bleach only kills surface mold, while vinegar can seep in and kill the underlying membrane, preventing the mold from growing back.
What To Do If Vinegar Doesn’t Completely Remove Mold Stains
In some cases, even after using vinegar to kill the mold, you may be left with unsightly stains. This is especially common with porous surfaces like wood, fabric, or grout. If vinegar doesn’t completely remove the stains, you have a few options.
For fabric items, try laundering them with a stain-removing detergent. For hard surfaces, you can try scrubbing with a paste made of baking soda and water, or using a commercial mold and mildew stain remover. In severe cases, you may need to sand and refinish wood surfaces, or consider replacing tiles or grout.
Can Vinegar Prevent Mold From Coming Back?
While vinegar is effective at killing mold, it’s not a foolproof solution for preventing mold from coming back. Mold thrives in damp, humid environments, so the key to preventing mold growth is to control moisture levels in your home.
After cleaning mold with vinegar, be sure to dry the area thoroughly. Use fans or dehumidifiers to remove excess moisture from the air, and fix any leaks or other sources of water intrusion. You can also use vinegar as a preventative measure by wiping down mold-prone areas regularly, but it’s not a substitute for proper ventilation and moisture control.
Is It Safe To Use Vinegar On All Surfaces?
While vinegar is generally safe to use on most surfaces, there are a few exceptions. Vinegar’s acidity can damage some natural stones like marble or limestone, as well as some wood finishes. It can also corrode metal over time, so be cautious when using it on metal fixtures or appliances.
If you’re unsure whether vinegar is safe to use on a particular surface, do a spot test in an inconspicuous area first. Apply a small amount of vinegar and wait a few minutes to see if any discoloration or damage occurs. If the surface remains unchanged, it should be safe to proceed with using vinegar to clean the mold.
