Shetland Cleaning the Fermented Suint Way

UPDATE: Since I started cleaning fleece in this manner, I've created a blog dedicated to the method.  Go here:

for a more comprehensive study.

I picked up an issue of Spin Off magazine wherein Judith MacKenzie McCuin gives a basic description of the Fermented Suint Cleanser method of cleaning fleece of excess lanolin. A method developed in New Zealand it is a very smelly process. But the environmental impact is low, no soap is needed or heat to heat the water.

You start out the mix by soaking a heavy grease wool in soft water. I used the rainwater Dale had gathered from the last rains and a heavy grease Rambouillet fleece. The suint (sheep sweat) that is on the fleece creates a natural cleanser made up mostly of potassium salts.

This is a shot of the Romeny fleece before it becomes submerged in the suint mix.

It is a beautifully clean fleece. There was hardly any VM (vegetable matter) in this fleece at all. Lovely lock formation

On this Shetland batch I decided to tray the locks to help maintain the lock formation.
I sorted them by grade.

This fleece had some yellow tips, it came cleaner with the Suint Soak that it did with soap and heat. Combed in it's not noticeable and with another washing it did come out. 

This tray was some of the finer wool with better tips.
Stacked the trays...

This is a shot of the suint mix. The more you use it the stronger it gets, but it smells pretty strongly. The top can form bubbles and a milky scum at the top. You can see a hint of it here.

I used the zippered laundry bags to help keep the fleece intact. This also makes it easier to rinse and move about from Suint Mix to rinse water.

I start by draining the FSM off of the fiber into another bin....save the runoff and pour it back into the original bin. Don't add any tap water to the FSM. Rinse by running water over the fiber until the water runs clear. This takes a few rinses. But it's good for the garden! I've stopped when the fiber is milky and it still comes free of the eau de Ferment after it dries.

....................After :) 

This method of scouring leaves just enough lanolin to work the wool nicely. No greasy gunky fiber here!

Delicious

Ready to spin.

This is a shot of one of the suint batches that didn't ferment properly. You can see there is algae growing on the surface rather than the milky white film that forms when it has working properly. I tried to start this mix with a fleece that already had been washed. If there is no suint your mix won't work...this get's tossed out.
