Fill washing machine with hot water and mix in 1 cup liquid laundry detergent. Once full, submerge fleece and close the lid, allowing the fleece to soak for 45 minutes (make sure your washing machine is off--if it actually washes the wool via agitation, you'll have an irreparably tangled mess).
Turn on the spin cycle. When the water is drained, remove the fleece, rinse the washing machine and repeat with another soaking cycle. Repeat as many times as needed to sufficiently remove the lanolin and dirt.
|Gross. Needs a few more cycles.|
It's a little difficult to tell from the photo, but trust me, it's much cleaner and smells soooo much better.
