Care of Stainless Steel
Maintain the natural beauty of stainless steel and 
prolong its service life by following these tips:
Ordinary deposits of 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.
Contact with dissimilar metals should be avoided 
whenever possible. This will help prevent 
galvanic corrosion when salty or acidic solutions 
are present.
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.
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.
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 whenever possible.
Discolorations or heat tint from overheating may 
be removed by scouring with a powder or by 
employing special chemical solutions.
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. 
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 washer-extractor. Damage 
of this kind is not covered by the manufacturer’s 
warranty. Locate the pump below the washer-
extractor’s injection point to prevent siphoning of 
chemicals into the washer-extractor. Refer to the 
chemical injection supply system in the 
Installation Manual.
