Just received 4 lbs. of yearling mohair fleece. I don’t see much vm, just some dirt. Dumped the whole load onto the floor and it all looks good, not many second cuts. I’m using crab boiling pots to wash the fleece. I have two. I fill the first with water as hot as the tap allows and then I boil a kettle and pour that in to raise the temp to around 130-140 degrees. To the hot water I add four squirts of Kookaburra Scour. I like the smell better than Power Scour.
About half the load or 2lbs of fleece go into the hot soapy water. Set the timer and let is sit for 20 minutes or more. Do not let it cool off in the wash water. Don’t forget it. The yolk that is melting off will reattach and be very difficult to remove on a subsequent attempts.
By now the first batch had released a lot of dirt.
When the first batch is ready to drain I take it outside and pour through a strainer. Press a few times to remove excess water. Then repeat. In the second wash, use half as much soap, the same hot water and same wash time. At the end of 20 minutes the water is dirty but relatively clear. Again, drain outside. To rinse the fleece, add more hot water to the pot and soak in water for 15 minutes or more. Drain. Continue to rinse in hot water until it is clear. Check the fiber and be sure it feels clean, not sticky.
At this point the wet fleece can be set outside to dry or left in hot water waiting for the dye pot.
