Tumbler for my SS baffles. Dental pics for aluminum. For bad build up I mask and filter up my face, turn on my air filter and hit em with the dremmel. Gotta have steady hands or you can go right through that aluminum depending on the bit you use. If you get a strong rpm dremmal and the “pen” attachment so you can hold it like your supposed to, some brass bits and brushes for it, and some time to kill, you could get your baffles looking like new. But baffles with a lite coat of dirty do sound better than brand new shiny ones.
