Did a Google on cleaning copper, and the most common cleaner for
copper pots appears to be vinegar and salt, or lemon juice and salt.
Maybe Worcestershire sauce has same ingredients?

The magic 8-ball known as Google seems to agree that you're right.
Most of the Worcestershire sauce recipies contain anchovies (quite
salty), and either vinegar or lemon or orange juice or some
combination thereof.

As to copper cleaners - one I remember favorably from my boyhood
puttering-with-chemistry days is a mix of sodium bicarbonate (baking
soda) and dilute ammonium hydroxide ("5% household ammonia water",
either clear or sudzy). The resulting slurry takes tarnish off of
copper or silver almost instantly (although I don't know how much of
the metal in the tarnish is returned to the surface and how much ends
up in the slurry).

Use with appropriate caution, gloves, and ventilation, of course.
