How can you determine whether anything is brass plated with this in mind?
With a magnet, you can detect whether something is solid brass or merely brass plated. It’s brass plated if the magnet clings to the object.

What’s more, how do you keep lacquered brass clean?
Simply dust it or wash it in gentle lukewarm suds, rinse it, and dry it with lukewarm water. If the water is excessively hot, the lacquer may be removed. Remove the lacquer with acetone (from a pharmacy) and polish if lacquered brass becomes dingy and the finish begins to peel.
