CLEANING
The Warmer and its

For all-pole disconnect,
unplug electrical power supply
before cleaning.
DAILY:
1.
Unplug electrical power supply.
2. Allow warmer to cool before

3.
Clean drawers and the interior of
the warmer with a mild soap and
water. Never use harsh
chemicals or abrasive pads to
clean the warmer.
4.
Dry with a soft cloth.
5.
Clean the exterior of the warmer

HEAVY-DUTY CLEANING:
For heavy-duty cleaning, use warm
water, a degreaser, and a soft rag.
Never rub in a circular motion -- rub
gently in the direction of the steel grain.
Always rinse thoroughly.
STAINLESS STEEL CARE
CLEANING:
Stainless Steel contains 70 – 80% iron,
which will rust if not properly maintained.
Stainless Steel also contains 12 – 30%
chromium, which forms an invisible
passive, protective film that shields
against corrosion.
If the protective film remains intact, the
stainless steel will remain intact.
However, if the film is damaged, the
stainless steel can break down and rust.
PREVENTIVE CARE:
To prevent stainless steel break-
down, follow these steps:
1.
Never use any metal tools,
scrapers, files, wire brushes,
or scouring pads (except for
stainless steel scouring pads,)
which will mar the surface.
2. Never use steel wool – which
will leave behind particles that will
rust.
3.
Never use acid-based or
chloride containing cleaning
solutions – which will break
down the protective film.
4. Never rub in a circular motion.
Always rub gently in the direction
of the steel grain.
5. Never leave any food products
or salt on the surface. Many
foods are acidic. Salt contains
chloride
