Mirror Repair

Unless it is something really special, you should replace it. It is possible to repair such a mirror, but it involves removing the reflective coating on the back and replacing it. Unless it is something really special that will be more expensive than just replacing it. You can not just clean it.

This is called having the glass "resilvered." Nowadays replacement with a new mirror is usually cheaper than resilvering: glass stores may tell you this process is suitable only for antiques.

If this isn't a special/ antique mirror and you simply want to repair it because the blotches are unattractive, here's another possible solution for you: If the blotches are in an unobstrusive area, e.g. in one corner or near the edges, you might try using an etching spray. This is available in spray cans, and as the name suggests, gives the mirror (or glass) an etched look. It can be applied over the blotches, either in a pattern with a stencil, or by taping off the desired section. Obviously this won't really fix your mirror and will cover the portions that you do spray, thereby making those unusable. But this technique might just make your mirror look nice enough to where you would be willing to keep it. I have no idea whether this is an option for you, but I thought I'd throw it out there. KB

IMHO, replacement might be your only option.
