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.

Use a non-chloride de-liming agent to remove line deposits.  It is important to use 

Lime

and Scale for Warmer Pans

 often to prevent a difficult-to-remove build-up of lime

deposits.

CAUTION: 

Personal Injury Hazard 

Disconnect appliance from electrical 

power before cleaning. 

USECO hot and cold pans are constructed 

of high quality stainless steel.  As long as 

the stainless steel surface in intact, the 

equipment will not rust or corrode. 

Recommendation: 

A water softening device or a cartridge-

type filtration device may be used to 

minimize lime and calcium build-up.
