Use Power Scour for wool washing and wool cleaning fiber with heavier burdens of grease, wax, suint, dirt and clay, typically found in sheep, goat and bison fibers.
Use lower temperatures, 40°-50°C (104-122°F), for fibers such as Cashmere, Alpaca, Bison ,etc. Use higher temperatures, 50°-55°C (122-131°F), for fibers with more oil/wax or oils (sheep, etc.)
This is the product I use to wash all my fleeces because it is the BEST!
I will be bringing it with me to Blue Hills Fibre Festival next weekend
