NEVER clean stainless steel with steel wool. It can deposit iron oxides into the surface of the ss and cause it to rust. You are much better off using something like a scotchbrite pad for polishing stainless.
NEVER use acid salts or caustic cleaners on stainless steel. It too can cause changes to the stainless on a molecular level which can lead to staining or even rusting. IE: "Lime away" will turn stainless steel permanently stained.
Soaking low grade stainless steel overnight in water can bring out the worst of it. Boiling low grade stainless and exposing the hot metal to air can flash rust it.

nautilus are actually stainless steel chimney and NOT plated brass crap like the authentic nautilus.
