Does saltwater stain stainless steel sinks?

Few people realize that stainless steel can still corrode like any other steel. The key to the corrosion resistance of SS is the high content of chromium as an alloying agent. The chromium in the steel combines with oxygen in the atmosphere to form an invisible later of protection. So in order for SS to resist corrosion it requires oxygen, in areas where oxygen is limited or circulation is poor corrosion can occur. Such areas are usually created with surface contact, for example if you place a glass in your sink and leave it for a long time you will get a rusty ring in your sink. You'll also notice your stainless coral sheers, despite your best efforts, will always rust in areas which always have surface contact.

So to some it all up, your sink can corrode but if you take proper precautions it can be prevented. However some areas of the sink with permanent surface contact will eventually corrode.
