Not usually an issue generally people want to stop rusting not not stop it. Salt water, heat and oxygen would probably work quite well. It would also rust faster if it had an increased surface area. Possible problems include the sacrificial metals that will be oxidised preferentially or metals with insoluble oxides being present in the sample that would protect the iron component.

∙ 14y agoA metal tarnishes due to oxidation. It forms an oxide layer on the metal.
eg: copper, when new it is shiny, but after a time outside, it goes green. This is due to
oxidation and is called a tarnish.

∙ 9y agoThere are several methods to prevent metals from tarnishing. If storing the metals, place several pieces of chalk with the metals and it will absorb the chemicals that create tarnish.

Is plutonlum a metal?
Plutonium is a rare actinoid metal with a silvery/white appearance. Plutonium tarnishes when exposed to oxygen in the air and forms a dull coating when oxidised. Plutonium is a transuranic radioactive element. Chemical symbol is Pu and atomic number 94.

Why is it chemical change when a silver fork tarnishes slowly in air?
Silver sulfide is formed on the surface of the metal.
Why you preferr gold as metal in jewelry?
sliver tarnishes much worse than gold and requires a lot of upkeep and can lose its shine
Why does potassium tarnish quickly?
Potassium tarnishes very quickly as it is extremely reactive, due to the fact that it has only a single electron in its outer shell. This makes it react quickly with oxygen, forming a layer of potassium oxide around the metal. If you cut the potassium, you will the see the true, silvery coloured metal for a few moments before it tarnishes again.
What is element 60 Nd?

Is jewelry tarnishes with age chemical or physical change?
It is a chemical change. Jewelry that tarnishes undergoes oxidation.
