To me, it seems like a waste of time--first ride on sand, dirt, or just a messy asphalt road, it's going to get black, again. I'm all for fun and games, but it seems like effort that will be for naught the first time the bike gets use.
For a show bike, I'd just buy a new chain, strip off the packing great, then oil. And make sure to not ride. Otherwise, it just seems like time not well spent.
I've taken to mineral spirits in a used salsa jar. I found the old trick of using a soda bottle to be annoying--the much wider opening on a glass jar is much easier to fish the chain out of. I just wish I could better filter the mineral spirts, but then again, when I clean my chain, which isn't often, it's good and truly loaded with dirt. After the bath, I do hit with a bit of brake cleaner, the chain won't quite fully dry out in the sun, and often I'm not waiting, so a quick attempt to get that off, then back on the bike. [Been using that Rock and Roll lube lately, not sure how well it would do with extra spirits left on the chain.]
