CARE OF ANODIZED ALUMINUM
(SC-7 & SC-11)
The well in your Wells Warmer or Soup Cooker is constructed of high quality anodized
aluminum. As long as the anodized surface layer is intact, the equipment will not corrode.
The anodized surface can be damaged by mechanical abrasion, hard water deposits and
chlorine:
1. NEVER use steel wool, wire brushes or metal scrapers to clean the warmer. These will
damages the anodized surface of the well. Metal scrub pads SHOULD NOT be used
on anodized aluminum.
2. Hard water deposits left behind when water is evaporated will attack the anodized
surface and allow the well to corrode.
3. Chlorides from chlorinated cleansers, calcium/lime/rust removes (e.g. muriatic acid),
even heavily chlorinated city water will attack the anodized surface and allow the well to
corrode.
4. DO NOT use any highly caustic cleaners on the warmers. Use of highly caustic cleaners
will attack the anodized surface and allow the well to corrode.
5. LIMIT USE of strong caustic cleaners on warmers. Rinse thoroughly with a vinegar and
water solution to neutralize any residue. Failure to do so may cause damage to the
anodized surface and allow the well to corrode.
6. Cleansers containing ammonia will attack the anodized surface and allow the well to
corrode.
Use the proper tool in the proper way to clean you Wells warmer:
1. Soft cloth and plastic scouring pads are safe to use on anodized aluminum. Scrub only
in the direction of the grain lines.
2. Do not use a circular motion.
Use only non-chlorine and non-ammonia cleansers:
1. DO NOT use any cleanser listed as “chlorinated”.
2. DO NOT use any cleanser listing “ammonia” or “ammonium” in its contents.
3. Contact your cleaning materials supplier for cleansers suitable for aluminum.
Keep you Wells warmer clean. Clean frequently to avoid build-up of hard, stubborn stains and
hard-to-remove deposits:
1. Rinse thoroughly with a vinegar and water solution to neutralize any residue.
2. For discoloration caused by using the warmer in DRY operation, use a cleaner made
specifically for anodized aluminum.
3. Wipe dry with a soft, clean dry cloth.
4. Restore the surface by using a polishing product specifically made for aluminum after
each cleaning.
Recommendation: A water softening device or a cartridge-type filtration device may be used to
minimize lime build-up.
