It depends on what result you want. R's jumper will be slightly water proof because we are spinning it before washing so some of the lanolin is trapped in the yarn still. I just pull out clips and seperate it out into locks. Then I comb it out with a wool comb (like a big dog comb) this gets most of the dirt and shit out of it. Then I spin it. Once it is skeined up we wash it quite a few times.
We don't have anywhere big enough to wash a whole fleese
