You don't have to be quiet 24 hours a day.
If you just want to "mask" the brass cleaning sound, put some Rammstein on!!!
what is a quiet brass cleaner? I don't care of its a tumbler or sonic or SS pins just needs to be quiet, I live in a apartment at the moment.
Give your wife a rag and a can of Brasso.
Ultrasonic is quiet... Makes a faint buzz like a bee in the room...
