Care and Maintenance of Stainless Steel
The following points on the care and maintenance of stainless steel surfaces should be observed in order to maintain the natural beauty and prolong its service life.
1.Cleanliness is of utmost importance. Common deposits of dirt and grease can be quickly removed with a detergent and water solution. Whenever possible, the metal should be thoroughly rinsed and dried after washing. Periodic cleaning will maintain the bright surface appearance and help prevent corrosion.
2.Deposits that adhere to the surface of 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 showing. Never use ordinary steel wool or steel brushes on stainless steel. Iron particles from steel wool and brushes made of carbon steel may become imbedded in the surface, causing rust. Use stainless steel wool or soft
3.Contact with dissimilar metals should be avoided whenever possible. This will help prevent galvanic corrosion when salty or acidic solutions are present.
4.Discolorations or heat tint from overheating may be removed by scouring with a powder or by employing special chemical solutions.
5.Salty or acidic solutions should not be allowed to evaporate and dry on stainless steel. They may cause corrosion. Wash off the solution after using.
6.Permanent direct contact with other materials, such as wood or carbon steel, should be avoided.
7.Sanitizers or sterilizing solutions should not be left in stainless steel equipment for prolonged periods of time. These solutions often contain chlorine which may cause pitting corrosion. The stainless should be cleaned and rinsed thoroughly after using.
8.Rust appearing on stainless steel sometimes leads to the belief that the stainless is rusting. The source of the rust may actually be some iron or steel part not made of stainless, 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 employed whenever possible.
CAUTION
Follow the manufacturer’s advice whenever cleaning agents or other chemicals are used, inside or outside the machine. Some cleaners may be poisonous or flammable, and improper use may cause personal injury or damage. Do not use volatile cleaning solvents such as acetone, lacquer thinners or enamel reducers. Never use carbon tetrachloride, gasoline, benzene or naptha for any cleaning purpose.
