Guidelines for Maintaining Stainless Steel Surfaces
There are three basic things that can break down the surface layer of stainless steel and allow
corrosion to develop: 1) Abrasion; Deposits and Water and 3) Chlorides.
Avoid abrasion from rubbing with steel pads, wire brushes or scrapers that can leave iron deposits on
stainless steel; instead, use plastic scouring pads or soft cloths. For stubborn stains, use products
such as Cameo, Talc or Zud First Impression. Always rub parallel to the polish lines or with the grain.
Hard water can leave deposits that promote rust on stainless steel. Treated water from softeners or
certain filters can eliminate these mineral deposits. Deposits from food must be properly removed by
cleaning. Use mild detergent and nonchloride cleaners. Rinse thoroughly. Wipe dry. If using chloridecontaining cleaners or sanitizers,
rinse repeatedly
to avoid stainless steel corrosion. Where appropriate,
apply a polish recommended for stainless steel (such as Benefit or Super Sheen) for extra protection
and luster.
