•For best results, always use pre-moisten towels with hot water. (do not wet towel completely, or use it straight from washing machine) •We recommend you preheat the cabinet without any towel inside for 20 minutes before placing any towels inside. • Warming times vary depending on the starting temperature of the towels, how wet the towels are, and the temperature of the room. • Please Note: Ensure to properly clean and sanitize every day. Remove towel / cloths at the end of day - leaving them over night may cause mold or mildew. Clean with mild soap inside and out. Do not use corrosive products. Leave door open over night.
