How to remove silver nitrate stains on skin

Updated February 21, 2017

Silver nitrate is a chemical substance that is used to develop photographs and in some medical procedures. If the substance comes into contact with the skin, it leaves a residue which will gradually darken to a black or grey colour over several hours. You can remove silver nitrate stains if they are caught early. Once the stain becomes fully developed, it is usually impossible to remove, but it will wear off naturally.
