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.
When metal tarnishes, it forms a layer of corrosion on its surface due to exposure to air, moisture, or other chemicals. This layer can give the metal a dull or discolored appearance. Tarnishing does not usually affect the structural integrity of the metal but can be removed through polishing or cleaning.
A 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.
There 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.
A chemical reaction - generally oxidation - occur on the metal surface.

Is technetium shiny or dull?
Technetium is a silvery-gray metal that can appear shiny when freshly prepared, but it can dull over time as it tarnishes in air.
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 quickly because it is highly reactive with air and moisture. When exposed to air, potassium reacts with oxygen and water vapor to form potassium hydroxide and potassium peroxide, which cause the metal to tarnish.
Is jewelry tarnishes with age chemical or physical change?
Tarnishing of jewelry is primarily a chemical change. It occurs when the metal reacts with substances in the environment, such as oxygen or sulfur compounds, leading to the formation of tarnish on the surface of the jewelry.
What is element 60 Nd?
Neodymium is an element on the periodic table of elements. It is abbreviated as Nd and has an atomic weight of 60. It is a silver metal that tarnishes in the air.
Is cesium shiny?
Yes, cesium is a shiny metal with a silvery-gold appearance. It has a high luster when freshly cut, but quickly tarnishes in air due to its high reactivity.
What does plutonium do look like?
Plutonium is a silvery-gray metal that tarnishes in air, resembling the appearance of other metals like nickel and aluminum. It is typically found in solid form and is dense and highly toxic.
