Does anybody know of a chemical type cleaner for cleaning heavily
tarnished brass? The item is a complex moulding and very hard to clean
with cloth and brasso which just reaches the more exposed surfaces.

The FAQ-to-be says either vinegar or tomato ketchup, which contains
weak acid + salt.

I've used vinegar on copper and it does a great job. Note the runoff in
either case is toxic.

Coke is a very weak cleaner, and not the right kind of acid for best
results.
