Care of stainless steel
Maintain the natural beauty of stainless steel
and prolong its service life by following
these steps.
1. Ordinary deposits if dirt and grease can
be removed with detergent and water.
The metal should be thoroughly rinsed and
dried after washing. Periodic cleaning
will help to maintain the bright surface
appearance and prevent corrosion.
2. Contact with dissimilar metal should be
avoided whenever possible. This will
help prevent galvanic corrosion when salty
or acidic solutions are present.
3. Salty or acidic solutions should not be
allowed to evaporate and dry on stainless
steel. They may cause corrosion. Ensure
that the stainless steel is wiped clean
of acidic solution residues.
4. Deposits that adhere to the stainless steel
should be removed, especially from
crevices and corners. When using abrasive
cleaners, always rub in the direction
of the polish lines or grain of the stainless
steel to avoid scratch marks. Never
use ordinary steel wool or steel brushes on
the stainless steel. Use stainless
steel wool or soft non-metal bristle brushes..
5. If the stainless steel appears to be rusting
the source of the rust may actually be
an iron or steel part not made of stainless
steel, such as a nail or screw. One
remedy is to paint all carbon steel parts with
a heavy protective coating.
Stainless steel fasteners should be used
when possible.
6. Discolorations or heat tint from
overheating may be removed by scouring
with powder or by employing special
chemical solutions.
7. Sanitizers or sterilizing solutions should
not be left in stainless steel equipment
for prolonged periods of time. They often
contain chlorine, which may cause
corrosion. The stainless steel should be
cleaned and rinsed thoroughly of any
solution containing chlorine.
8. When an external chemical supply
system is used, make certain that no
siphoning of chemicals occurs when the
washer-extractor is not in use.
Highly concentrated chemicals can cause
severe damage to stainless steel and
other components within the machine.
Damage of this kind is not covered by the
manufacturers warranty. Locate the pump
below the washer’s injection point to
prevent siphoning of chemicals into the
machine
