How to clean dirty wool hunting pants
Normally I take my wool clothes to the dry cleaners. I have some M-51 Army Surplus wool trousers that got really filthy with blood and guts when I gutted an elk in 2011 (the elk was laying on the side of a hill, guts came out of the elk down the hill, and I had to kneel there to work inside the chest cavity cutting stuff loose). I took them to the dry cleaners, but they didn't get them very clean. There is crap -- blood and probably gut material -- still caked on the pants.
Any suggestions about an alternative way to clean these pants? I've got a couple of other pairs of the same pants that are clean. These are cheap. If I can't clean the dirty ones, I'll just throw them away, but I hate to do that. I don't need pretty clothes to hunt in . . . I just don't want them to look absolutely like I've been wallowing in manure.
