Hydrogen peroxide can be used as a mild antiseptic to curb superficial skin infections such as athlete’s foot, but only in diluted quantities. To combat stinky feet, try soaking your feet in a solution of 1 part 3% hydrogen peroxide and 3 parts warm water for 15-20 minutes, then drying them thoroughly. This will kill odor-causing bacteria and soften your feet. To treat athlete\'s foot, you can use a similar solution, but only in diluted quantities, and soak your feet for 30 minutes.
Hydrogen peroxide can also be used to keep vegetables fresh by adding 1/4 cup to a bowl of cold water, soaking the vegetables for 20-30 minutes, then draining, drying, and refrigerating them. Alternatively, you can spray vegetables with a solution of 3% hydrogen peroxide and let them stand for a few minutes before rinsing and drying. To keep leftover salad fresh, spray it with a solution of 1/2 cup water and 1 Tbsp. 3% hydrogen peroxide, drain, cover, and refrigerate.
