Athlete’s foot, greasy hair and oily carpet stains may seem like unrelated problems with different solutions. But it turns out that a common household ingredient can be used to battle all three issues and many more. Cornstarch, that powder you probably tuck away with other cooking ingredients, can come in handy in a host of health and cleaning situations. Its soothing quality makes it an excellent remedy for skin problems, and its moisture-absorbing power and lack of scent make it a tried-and-true deodorizer. At prices as low as $1 per box, the ingredient also makes a far less expensive alternative to store-bought products. Learn about all the ways you can use cornstarch in your everyday life.
