While stainless steel is more durable and rust proof than other forms of steel, it can rust in the presence of certain common corrosive substances. Chlorine, among other things, can degrade the surface of stainless steel, allowing for the formation of rust. Proper cleaning and care of stainless steel surfaces is necessary to prevent the surface corrosion that will allow rust to form on stainless.
Rinse the stainless steel with large amounts of fresh water after contact with any corrosive materials, such as pool chlorine, bleach, acids or salt. Initial contact with any of these substances will not damage your stainless steel, but leaving them on the surface for a long period of time -- one or two days -- will cause pitting and rust to form.
Dry the stainless thoroughly with a soft towel to remove any standing water on the surface after rinsing or any contact with water.
Clean the stainless steel once a week with a nonabrasive cleaner, such as window cleaner or a cream cleanser for glass-topped stoves. Rinse thoroughly and dry with a towel.
