First get a bucket of warm water, not too hot, with a cup full of epsom salt. Allow salt to dissolve before placing your feet inside. Once the salt has dissolved, place your feet inside of the water, allow to soak for up to 30 minutes. 2 Remove feet from water after 3o minutes. Scrub gently with toothbrush to remove all loose, dry skin. This only takes a small amount of time. The skin should be very easy to remove. Rinse feet with water and pat dry with towel, need for summer!
