You can scour wool in just about anything you can find to fit it in. I usually use my kitchen sink (the double sink kind) or if you have a large garage or basement sink (the large, one tubbed kind) or even your washing machine (like Cynthia mentions to "dry" it out) You can also use those party tubs they sell to put ice and drinks in...those have nice sturdy handles to transport it from one place to another.

I usually follow the "rule" of ratio of water to wool by if there is enough water to let the material float, or room to move it around to let the dirt and sheep bits fall to the bottom of the "tub" As for the temperature, I go by what I can keep my hands in for a set amount of time...

Depending on the dirt content (ie how dirty the fleece is), a good 1/2 hour soak works pretty good...changing out the water after about 15 minutes and checking the fleece for how clean it is. If the fleece is really dirty, it might take multiple soaks/scours to get it to where you want to work with it.

I use Dawn soap for those really dirty fleeces (mud, sheep dip, dust, etc etc) and froth the bubbles up BEFORE putting the fleece in to avoid felting it and then setting it in, pushing it below the surface of the water. Otherwise, I just use hot water to dissolve the dust.

Squeezing out the fleece instead of wringing it out works the best, then either dropping it in the washer for a quick spin out, or laying it out on drying racks (old screen doors work wonders for this!)

In your single sinks and tubs, you will need to change out the water until your fleece is as clean as you wish it to be. That is the nice thing about the double sinks, you can drain one side, and have the other side filled as you clean out the other side that was soaking.

In your washer, you can set it to the large load setting so the fleece can float in the water (if you are doing large fleeces) but don't let it get to the agitate setting. AND, don't let the washer fill with the fleece in it...let the washer fill up first and then submerge the fleece...drain the wash tub, and then spin the excess water out on the spin setting...

Keep in mind that you won't get every bit of dirt, piece of straw, etc etc out of the fleece...this is where carding, combing, and final processing of the wool comes in.

Happy wool processing!
