The inside color is gorgeous, and my hopes were to clean it up so the outside looked just as good. Let's just say we ALMOST got there.
I did a little internet snooping around and came up with a plan of action that I would recommend if you have any interest in fixing up tarnished brass (which is super trendy right now; every single damn shirt I've bought this year has brass beads).
First, wash thoroughly in hot soapy water. Dry completely. This is what the bowl looked after that process; a little better, but not quite there.
Sprinkle salt on half of a lemon and rub the lemon into the sides of the bowl. This is a kind of natural scrub that also works wonders for your skin! lol.
The finished product (for now!). Seriously, I was really impressed with how much better it looked. It still looks a little scratched up and tarnished, but I think that gives it some Old World-charm. I think I might try one more round of paste at a later date, but I'm pretty happy with the results.
I should note that this was also my first foray into Heloise-style domesticity. I used to edit the Hints from Heloise column every week and if I learned anything, it's that the solution to everything is vinegar.
