Add Vinegar to a Spray Bottle
Pour undiluted vinegar into a spray bottle. Always use a new spray bottle, not one that contained other types of cleaners. Some chemicals when mixed with vinegar can cause problematic reactions. Label the bottle.
Opt for Scented Vinegar
If the smell of vinegar is too strong, you can make and use scented vinegar. Use herbs or add 10 to 30 drops of your favorite essential oil into the spray bottle. Some essential oils that mix well with vinegar are eucalyptus, citrus oils, or a blend of lavender and lemon. When blending oils, use 10 to 15 drops of each fragrance. Mix thoroughly.
Apply to Surfaces
Protect your eyes and skin from splashing by wearing rubber gloves and eye protection while cleaning with vinegar. Wear a protective mask to prevent the inhalation of mold spores.
Spray the solution directly on the mold, saturating it well. Leave the vinegar to work for at least 30 minutes to one hour.
Remove Mold and Stains
Once the vinegar has done its job and killed the mold, rinse the area well with water and wipe down the surface with a sponge or paper towels.
Use an all-purpose cleaner and a stiff brush to remove any stains from grout on tiled surfaces. For walls and fixtures, use a fresh sponge and a cleaner to remove stains by following the label directions on the cleaner.
Bag and Toss Sponge or Paper Towels
Place the sponge, paper towels, and brush used to remove the mold in a plastic bag. Tie the bag tightly and discard it in an outside trash container. This is to prevent mold spores from contaminating the rest of the house.
When to Call a Professional
If you catch mold growth while it is a small colony, it can usually be removed safely with home methods. However, if the mold growth is extensive, it is important to determine what type of mold you have in your home. If the mold infestation is deemed to be toxic or covers 10 or more square feet, then a professional should handle the removal. Local public health departments can offer advice on mold testing and refer you to an expert mold remover.
