There are polishes for stainless steel. I might try a scouring pad
first. The industrial solution is to soak it half an hour in 10%
nitric acid in a glass container.
Not all stainless steel is the same, and knives may rust before
flatware. Leaving stainless in contact with acidic or salty foods
can start rust. So can soaking it in contact with steel. Some say
stainless should not be washed in a dishwasher. However it's
washed, it should be towel dried.
Strong detergents *could* harm some kinds of stainless steel.
Otherwise, the two possible problems in a dishwasher are that the
stainless may be in contact with other steel items and it may stay
wet, at least at spots. "Rinse and Hold" is especially bad.
Years ago we had a set of stainless flatware that did fine in the
dishwasher except that sometimes there would be a rusty stain on
the blade of a table knife. Those blades must have been a
different alloy. I think scouring powder would remove those stains.
I think the blades are different because I get those little stains
sometimes, too, and can never figure out where they come from.
I have read that you shouldn't wash any kind of silver along with
stainless in the dishwasher, weather it be solid or plate. Does
something to the silver, but I can't remember what.
daughter was recently married and got new cutlery as wedding
gifts....think she is the one who told me the insert recommend avoiding
lemon scented dishwasher soaps as it is hard on them.
Hard to find dishwasher soap without citrus.
