Does the alcohol method leave any stains or spotting on the outside of the cases?
Yup. I've used it with mixed results.
Seems very few people heard of it till I brought it up earlier this year.
I did about 400 9mm brass in the oven at 200 for 1.5 hours. Appears to have come out dry! Didn't have as much success with .308, but maybe I should try both methods again.
