Kind of late to the discussion, but I would say no. Brass by it's nature, is always oxidizing, which is what causes the tarnish and can rub off on things. A surface that would be damp, could oxidize faster.

If you like a soft look, zinc or brushed stainless, would be better choices.

Having had brass items that are exposed to the air, no laquer finish, they need CONSTANT attention to look nice. Gets to be a real pain in short order. I sold the brass stuff, went to stainless steel which I love. Keeps the shiny finish with little to no work, even in extreme situations.

If you insist on the brass, Peek polish is very good. Seems to come from Canada, and a can lasts quite a long time.
