A:Answer The information that I have found on the Crock Pot website claims that the coating is not Teflon, but it is only described as a "proprietary non-stick coating". I too have wondered what coating is used, but I have been unable to locate any specific information; only the foregoing. I can say unequivocally that the non-stick properties thus far have been excellent, and the cleanup has been quite easy. I have also learned from other owners that the pot should not be cleaned in the dishwasher, as the caustic detergents cause rapid deterioration of the non-stick coating. Hand washing has been very easy, however.
