Although our appliances are stainless steel, improper use of any stainless steel product can rust its surface. Our appliances should be cleaned with a scouring agent and a scouring pad. Enclosed with your product should be a pipe cleaner for the glass gauge running through the appliance. This brush can also be used to clean the percolator. Use hot soapy water to scrub all other areas, but DO NOT use baking soda.
