A few questions:
1. The tag is pretty dirty. How do I clean that? I've seen some folks mention that they've used Q-tips. Should I do that? If I do, should I only use water, or should I mix the water with some kind of soap?
2. There's lots of grime in the usual places. Should I use saddle soap on those parts? Does anyone recommend something else? What about regular, old water and a toothbrush? That kind of freaks me out, but I'll do whatever you guys tell me.

Thanks, as always.
