How do you clean the inside of the gel warmer? As technologists use up the gel in a bottle, they invert the bottle to get the gel out easier and some becomes caked inside the warmer.

Disconnect the Gel Warmer from the electrical outlet prior to cleaning. The Gel Warmer may be cleaned by using a soft, damp cloth and a mild detergent or hospital grade disinfectant, such as ProteX ULTRA Wipes. Use care not to wet the electronic controls. Do not use an abrasive cleaner or isopropyl alcohol to clean the Gel Warmer. Do not submerge or immerse the Gel Warmer in water.
