My local hardware emporium has bronze wool. The plumbing/soldering section also has brass bristled toothbrushes that are indispensible for cleaning safely. A marine shop may be another source for the wool. I also use large brass cartridge cases, such as the 30-06, with flattened mouths to scrape thick rust. These items will not harm any remaining finish or actual patina. Good luck!
