Fill a small tub or bucket with hot water, as hot as can be endured. Soak the corn for an extended amount of time—ideally 20-30 minutes. If desired, keep a kettle of water on the stove, and pour more hot water into the bucket if the water begins to cool. Sand the corn down with a pumice stone. The hot water will have made the corn soft and much easier to scrub away. Use soft strokes in the same direction, much like petting a dog. Scrape with the stone until the corn is no longer visible. Liberally apply lotion to the affected area. This will delay reformation of the corn as long as possible. Rub the lotion into the former location of the corn as well as the area surrounding it. Cover with a sock or padded wrap. The corn should now be removed, but it will very likely return. To prevent it from returning, discover the cause of its formation. Make sure shoes fit comfortably and are neither too tight nor too loose, with room for the toes to relax. Use non-medicated corn pads. Visit a podiatrist for an accurate assessment of potential causes and permanent treatments.
