MAINTENANCE INSTRUCTIONS
CARE OF STAINLESS STEEL
1. The surface can be damaged by mechanical abrasion, hard water deposits and chlorine:
a. Never use steel wool, wire brushes or metal scrapers to clean the appliance.
These will damage the surface.
b. Hard water deposits left behind when water is evaporated will attack the surface
and allow the stainless steel to rust.
c. Chlorides from chlorinates cleansers, calcium / lie / rust removers (e.g. muriatic
acid), even heavily chlorinated city water will attack the surface and allow the
stainless steel to rust.
d. DO NOT use any highly caustic cleaners. Use of highly caustic cleaners will
damage the surface.
e. LIMIT USE of strong caustic on warmers. Rinse thoroughly with a vinegar and
water solution to neutralize any residue. Failure to do so may cause damage to
the surface and allow the stainless steel to rust.
f. Cleaners containing ammonia will attack the surface and allow the stainless steel
to rust.
2. Use the proper tools in the proper way to clean your USECO warmer:
a. Soft cloth and plastic scouring pads are safe to use on stainless steel surface.
b. Stainless steel pads may be used ONLY IF the scrubbing motion is in the
direction of the visible grain. DO NOT use a circular motion.
c. In the absence of visible grain, use only cloth or plastic pads. Scrub only in a
linear motion along the longest axis of the equipment.
3. Use only non-chloride and non-ammonia cleansers:
a. DO NOT use any cleanser listed as “chlorinated”.
b. DO NOT use any cleanser listing “ammonia” or “ammonium” in its contents.
c. Contact your cleaning materials supplier for suitable alkaline cleansers.
4. Keep your USECO hot and cold pan clean. Clean frequently to avoid build-up of hard,
stubborn stains and hard-to-remove deposits.
a. Rinse thoroughly with a vinegar and water solution to neutralize any residue.
b. For discoloration caused by using the warmer in dry operation, use a cleaner
made specifically for stainless steel.
c. Wipe dry with a soft, clean dry cloth
d. Restore the surface by using a polishing product specifically made for stainless
steel after each cleaning.
5. In areas where tap water has a high mineral content, warmers may develop lime deposits.
