Care of Stainless Steel
• Remove dirt and grease with detergent and water. Thoroughly
rinse and dry after washing.
• Avoid contact with dissimilar metals to prevent galvanic cor-
rosion when salty or acidic solutions are present.
• Do not allow salty or acidic solutions to evaporate and dry on
stainless steel. Wipe clean of any residues.
• Rub in the direction of the polish lines or “grain” of the stain-
less steel to avoid scratch marks when using abrasive clean-
ers. Use stainless steel wool or soft, non-metal bristle brushes.
Do not use ordinary steel wool or steel brushes.
• If the stainless steel appears to be rusting, the source of the
rust may be an iron or steel part not made of stainless steel,
such as a nail or screw.
• Remove discoloration or heat tint from overheating by scour-
ing with a powder or by employing special chemical solu-
tions.
• Do not leave sterilizing solutions on stainless steel equipment
for prolonged periods of time.
• When an external chemical supply is used, ensure no siphon-
ing of chemicals occurs when the machine is not in use. High-
ly concentrated chemicals can cause severe damage to stain-
less steel and other components within the machine. Damage
of this kind is not covered by the manufacturer’s warranty.
Locate the pump and tubing below the machines’s injection
point to prevent siphoning of chemicals into the machine.
