There are numerous ways to clean brass, including Brasso. I'd suggest you Google "Cleaning Brass" and then choose whatever option you prefer. I personally do not like 'polished' brass on anything. I grain it with very fine Scotch-Brite then clear coat it with laquer, if it's furniture related. For things that I like to handle, like guns, I grain the brass and then use furniture paste wax to temporarily protect it from oxidation. Brasso, Paste Wax, Lemon and Baking Soda, yadda, yadda, yadda. They all require about the same amount of work and brass demands routine maintenance to stay bright. It's your choice.
