Remedy For Dry Cracked Heels!!! Listerine: The BEST way to get your feet ready for summer. Sounds crazy but it works!!! Mix 1/4 cup Listerine (any kind but I like the blue), 1/4 cup vinegar and 1/2 cup of very warm water. Soak feet for 10 minutes and when you take them out the dead skin will practically wipe off!!!
