Quote:
Spreading a tomato product( ketchup, taco sauce) will clean the tarnish off copper, silver and brass. But smooshing a tomato on it will not.
I wonder why?

Ketchup, used primarily as a condiment, is a sweet-tart sauce whose main ingredient is tomatoes, flavored with onions, garlic,
vinegar, sugar, and spices.
Plain vinegar will remove tarnish, so I suspect Ketchup's effect is due to the vinegar it contains.
