I wash all wool in the front loader with enviro detergent (it's what I use for all my laundry) and no softener (again, like all my laundry). The wool then gets hung to dry (like all my tech stuff) with the exception of the socks, which go in the dryer.

Honestly, the hardest thing on my wool? My belts. If I wear wool t's or l/s tops with jeans or something where I'm wearing a belt and I don't tuck in the shirt, it gets holes where it covers the belt...presumably from wear/damage. Kind of annoying but mostly my own fault. It's a pretty rare way of wearing my wool though and no, I can't really skip the belt (see any thread here about monster quads to see why )

My husband uses the same washing methods as me, but he puts most of his stuff in the dryer. With the exception of looking slightly more 'lived in' than my wool stuff, his things are holding up great.(mostly ibex, smartwool and icebreaker).

Oh, and I wear wool socks all year too...at least for exercise. I don't wear socks in the summer at all unless I'm exercising though.
