So now for a bit of polishing, the parts have had a soak and I’ve cleaned the top cover of the mainspring barrel with…. a brass cleaner 😆 It has a tarnish inhibitor so the finish will last longer, everything MUST be like a mirror 
My thang.
You can’t really see because of a bad shot, but the cover is now a gleaming, deep gold color mirror, as opposed to the barrel.
I like to clean by hand, I’ve used an ultra sonic but I prefer my own method, plus I can do a thorough visual inspection.
I made a few cleaning jigs out of wood, so I can accommodate most parts and clean them securely, keep them flat, and not worry about bending them.
