Use a soft-bristled scrub brush or rough sponge to gently scrub all of the mold growth off the wall*
Wipe with a fresh, wet rag and then dry with a new cloth
After removing the green or black mold, lightly spray the area with vinegar and allow it to dry. This will help kill any remaining mold spores.
*If you don’t have a scrub brush, you can use a regular cleaning rag with a little bit of baking soda. The baking soda is slightly abrasive, so it will help remove the mold growth without damaging the wall.
How Much Vinegar Should I Use To Kill Mold On Drywall?
You don’t need a ton of vinegar to kill the mold on your drywall – simply saturate the moldy spots and surrounding areas. Then, allow the vinegar to sit for an hour before scrubbing the wall.
After cleaning, you can follow up with a very light spray of vinegar to kill any remaining spores. You don’t need to rinse this coating off.
Be sure to use undiluted white distilled vinegar. If you dilute the vinegar, it won’t be strong enough to be effective.
How Long Does It Take For Vinegar To Kill Mold?
It takes vinegar approximately one hour to kill mold. If you’re dealing with very heavy mold, wait longer than an hour or treat the area twice.
If you’ve found mold on your drywall, you’ll be happy to know that white distilled vinegar is a proven method for killing it. However, vinegar doesn’t kill all types of mold, so if you see mold growth in the area you treated, you may need to call in professionals.
Also, if you’re dealing with a moldy area of more than 10 square feet, the EPA recommends calling in a professional mold removal crew.
