This silver sulphide tarnish can be quite easily removed using polishes that contain abrasives to rub off the silver sulphide, but these have the disadvantage of also removing small amounts of silver. Handily, chemistry provides a method which sidesteps this problem.
A chemical reaction means molecules of one kind are changing to molecules of something different. For example, a chemical reaction occurs when we use an acid rust remover. This does not physically remove the rust. Rather it changes the rust to a new substance that is colorless.o use pH paper, moisten the stain slightly with water and press a piece of Phydrion paper to the carpet and check the color of the paper on the pH chart provided. Some of the color may transfer to the fibers. A safer way is to scoop up some of the moisture from the stain and apply this to the pH strip.
