Cleaning
STAINLESS STEEL EXTERIOR
Use a nonabrasive stainless steel cleaner and apply with a
soft lint-free cloth. To bring out the natural luster, lightly
wipe the surface with a water-dampened microfiber cloth
followed by a dry polishing chamois. Always follow the
grain of stainless steel.
INTERIOR CLEANING
To clean interior surfaces and all removable parts, wash
with a mild solution of soap, water, and baking soda. Rinse
and dry thoroughly. Avoid getting water on the lights and
control panel.
CAUTION
Do not use vinegar, rubbing alcohol, or other
alcohol-based cleaners on any interior surface.
VACATIONS
For extended vacations, turn power off at the control
panel. Empty the unit and block doors open slightly to let
fresh air in and keep the interior dry.
