Vinegar kills 82 percent of mold, according to green living expert Annie Bond. She advises spraying straight vinegar onto mold and allowing it to dry without rinsing. To improve the smell of vinegar, try adding a few drops of your favorite essential oil.
Tea Tree Oil
Sharon Delia, environmental health researcher, says that tea tree oil permanently removes the smell of must and mold. Dilute only a few drops in 2 cups of water and spray on moldy areas and allow to dry without rinsing. Tea tree oil can be found at most health food stores. It has a strong smell that will dissipate within a few hours.
Grapefruit Seed Extract
Grapefruit seed extract can be purchased at most health food stores. Use about 20 drops in 2 cups of water and spray onto moldy areas. Allow the area to air dry.
