You can wash wool with salt or a wool washing powder and i recently discovered was a biological dish soap. I had already sorted the wool that i am going to wash by length and my fleece was reasonably clean.
I use very little dish soap 2 super tiny teaspoons.
I put the wool in bundles with the points forward in a landry bag.
Then i fill two buckets with 5 liters of hot tap water and another one liter per bucket of boiling water.
When both buckets are filled, i put de dish soap in a bucket and the laundry bag goes into the bucket.
With a whisk i gently push the wool under water and the color changes immediately.
Afer half anhour i take the bag out of the water and gently push the wool into the sink. Now i put the bag in the other bucket to rinse the wool clean. After 10 minutes i take the bag out of the water and gently push the wool into the sink.
I’am going to dry the wool with a salad spinner.
Then i put the wool on a dring rack with a towel on it, in the house and after 2 days the wool is dry and soft and smells nice 🙂
The wool goes into a transparent container, sorted of course, ready for use. Sorting out, washing and combing the wool is a relaxed activity for me to discover how it will all look at the end.
