Cure Acne. Use a cotton ball to dab Listerine on blemishes.
Fertilize a lawn. Jerry Baker, author of The Impatient Gardener, suggests mixing one cup Listerine, one cup Epsom salts, one cup liquid soap, and one cup ammonia in a one-quart jar, filling the rest of the jar with beer. Spray this on up to 2,500 square feet of lawn with a hose-attached sprayer in May and again in late June.
Use as a deodorant. Listerine helps kill the bacteria that cause perspiration odor. Dab it under your arms.
Eliminate mildew odors. Wipe with full-strength Listerine.
Disinfect wounds. Listerine works as an astringent when poured on a laceration or abrasion.
Disinfect a washing machine at a laundromat. To avoid getting germs from another family, wipe off the surface of the machine with Listerine and add one-half cup Listerine to the wash cycle to disinfect the machine.
