There are many different stores that offer wool wash, I like ones that have the lanolin in them. I decided to start taking pictures after I had started washing which is why the water is cloudy in the first pic. And I was taking pics myself so I couldn't really show action shots LOL.
Fill your sink with room temp water and submerge the wool. I always turn my wool inside out so that I am cleaning the inside. You will have to push it under to get the air out and get it fully wet.
Use your wool wash bar to scrub the wool all over. I usually start with the legs. I rub the bar to get soap on the wool then rub it in with my hands.
This picture shows the lather I have worked up on the leg.
When you have washed it all focusing on the "wet zone" then let it set in the water for about 10-15 minutes.
Now you drain the water and rinse the wool with room temp water again.
Then I squish water out of it. You do not want to squeeze or wring the wool.
Then lay it flat on a towel and roll it up like a burrito.
Step on the rolled up towel to squeeze excess water out of the wool.
This is where some people just lay the wool to dry but I have recently started putting mine on the spin cycle of the washing machine and letting it spin out as well.
Then lay flat to dry. I usually turn mine over every 8 hours so that it dries evenly.
