Hi Helen,
The tray is likely leaded brass. Brasso does not work very well on leaded brass. I don't know of a home remedy that will work well for you. You could take the tray to a professional plater in your area and they can properly clean and polish it for you. The chemicals used to properly clean the piece are not suited for home use.

Try 5% ammonium citrate(mix 50 gm citric acid ⇦ this on eBay or Amazon [affil links] /1 lit water and some ammonia,pH must be 9),or only citric acid /water solution.Hope it helps and good luck.
