Cleaning the Stainless Steel Casing
The stainless steel surface of your MAYTAG Whole Home Water Filtration System requires no special maintenance. If required the surface may be cleaned using a mild soap solution. Do not use any other cleaners or abrasive materials on the stainless steel surface as these cleaners may damage the label. Wipe the System dry with a soft cloth afterward.
