Maybe...a soft bristled tooth brush, and some mild soap and warm water and a soft rag. PLEASE...dont take a wire wheel to it...that reminds me of them dudes on Rick's Restoration just GRINDING and POLISHING that beautiful patina off those beautiful, old brass, bronze, pewter and aluminum antique parts and pieces. And then the customer comes to pick it up and is like "OMG THATS AWESOME..."Sure it is nice and shiny and looks good, but to a real historian/collector the real beauty is that natural, soft patina that lets the age, beauty and the history through. VERY nice piece!! thx ddf
