Care of stainless steel
Maintain the natural beauty of stainless steel and prolong its service lift by following these
steps.
1.
Ordinary deposits if dirt and grease can be remove 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 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.
Discoloration or heat tint from overheating may be removed by scouring with powder or by
employing special chemical solutions.
7.
Sanitizes or sterilizing solution 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
