Need advice on polishing brass items

[csziggy]

7. As I said, doing it by hand is too much for my old hands

I'd rather save them for doing my needlework.

I also have some other metal items that are not brass and some things that are mounted on wooden bases, so I'm thinking Flitz with the Dremel would be safer than anything that needs rinsing and especially might need soaking like the vinegar method. I can tape off the wood parts when polishing with the Dremel to protect the wood.
