I tried the oven method some time ago. Thought is would be a good idea....Forgot about the brass. Not sure how long it was in the oven...maybe an hour. The brass turned dark with spots....so I just do the towel method now and leave it to dry under a hanging lamp that I drop to about a foot over the brass. There is no water left on the outside when I set it to dry and I have never seen any spotting that way.
Agree .. Moved from oven to forced air duct in winter , and sun and wind ( outside ) in the spring/summer/fall
