We use wool wash from Northern Essence, but we've also used Sudz N Dudz wool wash. We put a bit of the wool wash into a container (some people just use the sink) and then a drop of lanolin (I use leftover Lansinoh). I fill about half full with really hot water and then let everything dissolve and add warm water so the water is warm when I put in the wool to wash it. If I need to clean the wool first (because it has poop on it etc) I use a wool wash bar by Sudz N Dudz and warm water and then soak it using the above mixture. I always leave it to soak for at least half an hour, but have forgotten the wool and it has soaked for 2 or 3 hours before with no problems. When I take it out I roll it and press out water and then roll it in a towel and press hard to get out as much as I can. Then I hang it to dry and it is normally dry in about 24 hours.
