Cleaning yarn?

[kixeldorado.livejournal.com]

Okay, so when I went to visit my family this weekend, my gram said "I was cleaning and found this yarn, do you want it?" It's a skein of brown and a skein of this 70's-esque light brown. Not colors I usually go for, but like I'm gonna ever refuse yarn. :)

Well, it's been sitting around a LONG time.
It's a little dusty and musty and could stand some cleaning before I try to use it.

The label says its "100% Virgin Wool" so how would I go about washing all the dusties and such out of it? She said it was in a cedar chest, so I'm not so concerned about bugs, but it could stand a rinse or something. But it's wool. Can you wash wool?

(If all else fails, I could just kind of put them in a frame and make some sort of shadowbox thing, because the labels are actually in really good condition for as old as I think they are).

I thought I'd run it by yall and see what kind of ideas you had. Help!
