Although specialized non acidic products can remove surface rust on marble or limestone the indwelling rust caused by constant induction of humidity mostly from the backside of the stone cannot be removed.
Why are structures that contain marble damaged by acid rain.
Acid rain rain is called acid rain only if it has more acid than normal.

Visit byju s to learn more about it.
When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves.
Trees that are located in mountainous regions at higher elevations such as spruce or fir trees are at greater risk because they are exposed to acidic clouds and fog which contain greater amounts of acid than rain or snow.
What man made structures is most susceptible to damage by acid precipitation.
When sulfurous sulfuric and nitric acids in polluted air react with the calcite in marble and limestone the calcite dissolves.
Structures made of iron and copper materials are also susceptible.
Structures made of limestone and marble are susceptible to damage by acid precipitation.
On non acid resistant stones like limestone or marble rust can be a non repairable problem.
Structures made of limestone and marble are.

Regular rainfall contains weak acid.
But human intervention and releasing of the massive amount of toxic into the atmosphere.
