Tantech makes some wonderful fibre treatment products that can clean and treat your wools, silks, and other natural materials for spinning and other crafting activities. The solution is safe to touch and doesn’t produce any irritating fumes or vapors. As a person with asthma, this could not be more important to me. As you can see in the video, the results speak for themselves. If you’ve been looking for something to make clean your fibres a breeze, I highly recommend Queensland’s own Tantech Fibre Scour!
