Care and Cleaning of
Stainless Steel
Introduction Stainless steel is steel alloyed with chromium to make it highly
resistant to stain, rust and corrosion. Note: This does NOT
mean that stainless steel will never rust or corrode. Science has
not yet developed a steel which is completely stainless or
corrosion PROOF.
The type of stainless steel and finish selected by SSCI for the
Oxygen Therapy Door is the best available for the intended use.
The basic rule of thumb is to use the mildest cleaning procedure that
will do the job effectively. Always rinse thoroughly with clear water,
and dry completely. Frequent cleaning will prolong the service life of
stainless steel equipment and will help maintain a bright, pleasing
appearance.
Ordinary deposits of waste and fluids can usually be removed with
soap and water. More stubborn deposits or tightly adhering debris
may require harder scrubbing and possibly the use of commercial
cleaning products acceptable for use on metal surfaces. When using
any cleaning agent, rub in the direction of the polish lines or “grain”
of the metal. For high luster finishes, clean soft cloths or pads should
be used.
If especially rough cleaning is necessary, use “stainless steel” wool,
nylon or plastic scrubbers. Test these scrubbers in an inconspicuous
area first to be sure they do not mar or scratch the stainless steel
finish.
Minor scale build-up and some hard water spotting may be
removed by washing with vinegar, followed by a neutralizing rinse
with clear water and a thorough drying with a soft cloth. For heavy
deposits of scale, 5% oxalic acid (use warm), 5-15% sulfamic acid,
or 5-10% phosphoric acid may be used. Always follow with a
neutralizing rinse of clean water and a thorough drying.
