Baking soda. One of the best ways you can treat corns and calluses is with a warm-water soak. This loosens the dead skin and helps with healing. Add 3 tablespoons baking soda to a basin of warm water and soak. Or massage calluses with a paste of 3 parts baking soda to 1 part water.
Chamomile tea. Soaking your feet in diluted chamomile tea can be soothing and will temporarily change the pH of the skin to help dry out sweaty feet. The tea will stain your feet, but the stain can be easily removed with soap and water.
Cornstarch. Sprinkle cornstarch between your toes to keep the area dry and protect the skin from breaking down. Moisture can make a corn or callus feel miserable and can promote fungal infections.
Vinegar. Soak a cotton ball in vinegar and tape it to your corn or callus. Leave the vinegar-soaked cotton on overnight. In the morning, rub the area with a pumice stone.
Pumice stone. Pumice powder and stones are used for scouring pans and are very useful for sloughing away dead skin. After soaking your foot in warm water for about 20 minutes, use a pumice stone to rub away those corns and calluses
Ice. Hard corns can be particularly painful. If you find yourself with a hard-core corn, apply an ice pack to the area. This will help reduce swelling and ease the pain a bit.
