I'm a convert too - use them in my Mustang and will one day get around to making a 25 ACP plug for the X7.

I have a small wide-mouth pill bottle filled with vinegar in my shooting bag. I just drop the fired cases in it and shake it around a little. They come out pretty darn clean and there's no need to do anything else but dry, de-prime and re-prime them. It seems to work best if you put them in within an hour or so of shooting. Don't leave them in the vinegar more than thirty minutes or so. Too long and they crud up again.
