There are 150,000 ways of washing wool. Some like to use a Suint mix, which is where the fleece is left to sit in rainwater for a week and it begins to ferment. Some people like to use Dawn Dishsoap. some like to use a product called Power Scour, and so forth and so on. I will say that you
should not use washing soda on a fleece as it will destroy the wool.
Myself however, I like to take the fleece put it into a mesh laundry bag from Walmart, rinse the fleece in
hot water to knock of the loose dirt, then I do about 4-6 tablespoons of Borax and the same amount of shredded bar
soap for every 1.5 lbs. mix it thoroughly so everything is homogenized. let it sit for about 20 minutes in
hot water, and then gently squeeze everything out being careful not to agitate it so you don't felt it. Fill the tub with hot
water again and rinse, and then repeat until the water is clear. After I let it sit for a couple of days to fully dry, I'm ready to start carding/ combing and spinning.
