If you "repair" the aging by removing the silvering and end up with a like-new mirror you have probably ruined the value. Same thing with sticking doo-dads over the spots. If you decide to go ahead, check and see if there is any value to the frame, too. Even if the frame only has decorative value, t's very easy to spoil a nice frame, so be careful.

If you don't believe me, do a search on the Home Depot, Lowes, or Ace Hardware sites and see for yourself. Mirror silvering is deposited onto glass via the silver nitrate precipitation method. The only way to remove it is through and acid-reduction reaction. The only products available to consumers that will do this are Sno-ball toilet cleaner or Muriatic Acid (available in pool supply stores). Both are very caustic and can cause severe burns and blindness if you are not careful in wearing eye, skin, and breathing protection. Yes, a do-it-yourselfer can do this project if they have very good ventilation, but do not let this post mislead you into thinking it is as easy as spraying on and wiping off some non-hazardous mystery product that doesn't exist.
