Before using file, we recommend soaking your feet in warm, soapy water to cleanse and soften skin. With repeated strokes in the same direction, move the file across the affected area to take off unwanted skin. To avoid redness, irritation and the removal of healthy skin, spread usage out over several periods so you do not over-file your skin. Healthy PediTips: For best results, apply moisturizer to feet after use. Regular use of this file helps keep feet soft and well-groomed day after day. Care: Hand wash your 2-sided Foot File with mild soap in lukewarm water. Rinse thoroughly. Air dry completely away from heat and sunlight before reuse.
