Cleaning and Preventative Maintenance
Protecting Stainless Steel
It is important to guard against corrosion in the care
of stainless steel surfaces. Harsh, corrosive, or
inappropriate chemicals can completely destroy the
protective surface layer of stainless steel, epoxy or plastic.
Abrasive pads, steel wool, or metal implements abrade
surfaces causing damage to this protective coating and
eventually result in areas of corrosion. Water can contain
high to moderate concentrations of chloride, causing
oxidation and pitting that results in rust and corrosion. In
addition, acidic spills that remain on metal surfaces are
contributing factors in corroded surfaces.
Proper cleaning agents, materials, and methods are
vital to maintaining the appearance and life of this
warmer. Spilled items should be removed and the
area wiped as soon as possible but at the very least, a
minimum of once per day. Always wipe standing water as
quickly as possible.
NOTICE: Always follow appropriate state or local health
(hygiene) regulations regarding all applicable
cleaning and sanitation requirements.
Cleaning Agents
Always use the proper cleaning agent at the
manufacturer’s recommended strength. Contact a local
cleaning supplier for product recommendations.
Cleaning Materials
Cleaning can usually be accomplished with the proper
cleaning agent and a so, clean cloth. When more
aggressive methods are needed, use a non-abrasive
scouring pad on dicult areas and make certain to
scrub with the visible grain of the surface metal to avoid
surface scratches.
How to Clean the Warmer
1. Disconnect the warmer from the power source.
2. Remove and wash any detachable items such as the
support assembly with hot, soapy water. Dry with a
clean, lint-free cloth.
3. Clean the interior and exterior of the warmer with
a mild soap and water solution. Apply the solution
with a clean, damp cloth. Do not use commercial or
household cleaners that contain ammonia.
NOTE: Make sure to wipe the control panel, door vents,
door handle or door button, and door gaskets.
4. Remove all detergent residue from the interior and
exterior of the warmer with a clean, damp cloth.
5. Dry the interior and exterior of the warmer with a
clean, lint-free cloth. Leave the door open until the
interior is completely dry.
6. Sanitize the interior of the warmer with a sanitizing
solution. This solution must be approved for use on
stainless steel surfaces.
7. Clean the warmer glass with glass cleaner or
distilledvinegar.
8. Replace the support assembly.
(IPX-0 - Listed as Ordinary)
WARNING
To prevent serious personal injury, death, or
property damage:

interior or exterior with water or liquid solution
of any kind. Do not use water jet toclean. Failure
to observe this precaution will void the warranty.
WARNING
Electric shock hazard.
Perform lockout/tagout procedures before
cleaning or servicing this appliance.
NOTICE: To protect surfaces, never use abrasive cleaning
compounds, chloride based cleaners, or
cleaners containing quaternary salts. Never use
