      It does reduce the metal a light amount, as the tarnish is part of the metal that has changed it’s composition. Wouldn’t take many cleanings to remove the silver form a mirror.

      We used to use Tarn-X for restoring Daguerrotypes and tintypes until it was found out that after a few cleanings, the silver was going away.

      Third thing, be careful with Thiourea, the active ingredient in Tarn-X. It is a carcinogen. So not a substitute for ketchup on hot dogs.
