Kookaburra Scour degrease your fleece.

Using Kookaburra Scour  1 Pound of wool:
Fill your sink with hot water. Depending on the amount of grease add 1-2 oz. of scour and immerse fiber.  Allow fiber to soak until the fiber feels clean to your touch.  (Each spinner has a personal preference for the amount of oil they prefer in the fiber as they spin). Drain excess water. You may rinse, but rinsing is optional.  Air dry.

Hints for first timers: You can squeeze the moisture from your fiber or you can put fiber into a net bag. Place bag into your washing machine and using the last section of your spin cycle, (no water cycle) spin excess moisture from your fiber.

White fleece may be dried in the sun, however, it is best to dry colored fleece out of direct sunlight.
