Does Vinegar Kill Mold? (DIY Spray Instructions)

How to Clean Using Vinegar

Distilled white or cleaning vinegar is a particularly effective, non-toxic product for cleaning mold from refrigerator interiors and gaskets, other kitchen appliances, and bathrooms.

1. Wear Protective Gear

   Since many molds can cause allergic or toxic reactions, protective eye gear, an N-95 mask, and rubber gloves should be worn while cleaning moldy surfaces. It's a good idea to wear old clothing that can be tossed in the washer so that mold spores will not be transported to other home areas.

2. Ventilate the Area

   Open doors and windows and turn on bathroom or kitchen exhaust fans to help ventilate the area before you begin cleaning.

3. Apply the Vinegar

   Pour undiluted vinegar into a spray bottle and label it. Spray the moldy surface. Allow the vinegar to remain on the surface for at least one hour before moving to the next steps.

4. Rinse the Surface

   Dip a sponge in clean water and wipe down the surface. Rinse the sponge frequently. For vertical surfaces, start at the top and work downward to catch drips.

   For porous surfaces, wring the sponge, so it is just damp to prevent oversaturating the finish.

5. Inspect for Discoloration

   If the mold has left grout or other finishes discolored, use oxygen-based bleach to remove the stains. Oxygen bleach will not kill mold spores but is very effective for removing stains.

6. Remove Discoloration With Oxygen Bleach

   Mix one-half cup of powdered oxygen bleach in a bucket containing two quarts of warm water. Stir well to dissolve the powder. Apply the solution to the discolored areas with a sponge or nylon-bristled scrub brush (a brush is best for grout). Allow it to work for at least 30 minutes, then rinse with clean water.

7. Dry the Surface

   Allow the freshly cleaned surfaces to air-dry.

   Tips

   • Vinegar can treat mold and mildew on clothes and accessories. Take the items outside to brush away as much surface mold as possible. This prevents mold spores from spreading inside your home.
     
   • If the item is washable, use the hottest water recommended on the care label and add one cup of vinegar to the washer load. If stains remain, create a solution of oxygen bleach and water and allow the clothes to soak for at least eight hours. Dry it with the sun (if possible).
     
   • Wipe down the surface of leather clothes, shoes, and purses with distilled white vinegar outside. After removing the mold, use a good leather soap and dry with a soft cloth. Allow the items to air dry completely, then treat them with a leather conditioner.

How Often to Clean Away Mold With Vinegar

When you discover a small mold colony, immediately clean the area. Small colonies can explode into large colonies in just a few days. Any area with high humidity or possibly leaks should be cleaned and checked at least weekly for signs of mold. Keeping surfaces clean helps eliminate the fuel (body soil, crumbs, moisture) that mold needs to thrive. 

When to Hire a Professional for Mold Removal

Smaller mold growth areas caught early can be removed with basic cleaning supplies and by following safety guidelines. Get mold removed professionally if the mold colony covers over 10 square feet (roughly a three-foot by three-foot patch). Hire a professional mold removal company to test and identify the type of mold present. Your local public health department can offer advice on mold testing and refer you to a mold remediation company.

• Use a dehumidifier and HVAC systems to help reduce inside humidity levels.
• Install moisture barriers in crawl spaces and basements.
• Clean mold-prone areas frequently to keep mold growth in check.
