So what's happening and how do you stop it? Mirror Rot is caused by moisture penetrating between the layer of glass and the layer of metal. Once water vapour has wormed its way in, the metal that makes your mirror shiny begins to react and oxidize (rust), turning an ugly black.
You can restore your favorite mirror to its original luster with a re-silvering process. Even though a glass professional can remove the backing, strip the remaining silver, and apply new silver, this process is complicated and can get expensive. Instead of re-silvering your mirror, consider: Mirror replacement.

Whether new or old, many mirrors desilver at some point during their lifetime. Dark edges around the outside of a mirror is a telltale sign that the silver backing is lifting and being worn away.
