I usually wash all my cashmere, wools, and fine knits by doing this:

1. Soak it in a bucket with Eucalan Wool Wash as per the directions
2. Hand squeeze out the excess gently (no need to rinse)
3. Put it flat on a dry towel, roll it up like a sushi roll and squeeze out all the water possible
4. Hang it on these hangers once it looks semi-dry and won’t be too heavy on the hangers to hang and become misshapen like so:

Then, I roll up the sweaters and store them safely.
