I payed 25 for them at Play it Again Sports. The heads looked to be in good condition, and the original grips had been replaced with somewhat newer Golf Pride Tour Wrap grips. I'm a sucker for old clubs, so I couldn't pass it up.
I'll have to give that bleach water a try. Last night I picked up a small Dremel rotary tool and a few polishing brushes at Wal-Mart for 20 bucks or so.

Still can't get to the small crevices, but definitely made a huge difference on the pitching wedge. I'll post up some before and after pics later.
Dremel has a few little golf project "tutorials" on their website:
- Replacing golf club grips
- Cleaning golf club heads
