Fingerprints
and Stains―Fingerprints and mild stains resulting from
normal use in consumer and architectural applications are the most
common surface contaminates. Fortunately, these fingerprints and
stains usually affect only appearance and seldom have an effect on
corrosion resistance. They are easy to remove by a variety of simple
cleaning methods. Fingerprints are probably the most troublesome
marks to remove from the surface of smooth polished or bright
finished stainless steel. Fortunately, they can be removed with a
glass cleaner or by gentle rubbing with a paste of soda ash (sodium
carbonate) and water applied with a soft rag. Once again, this should
be followed by a thorough warm-water rinse. There are several special
surface finishes where fingerprints present special problems:
polished No. 6 finishes, some abrasive blasted finishes, and light
electrochemical colors applied over satin or brushed finishes.
(Note:
There are several special finishes designed to withstand
fingerprints: embossed, swirl patterns, lined patterns, etc.)
