Soak hands in cold water with a little soap. Gently rub and squeeze the coat to remove the water and dirt. Repeat several times.
Drain the water, then fill the sink with clean cold water. Squeeze the fur to remove the soapy water. Repeat several times.
Drain the water, then squeeze the fur to remove as much water as possible. Dry on a line dryer, flat if possible.
Put your hands in a pillowcase, or any other cloth bag of sufficient size, and close it tightly. The bag will protect the fur on the drum and limit rubbing.
Put the appropriate soap in the machine, then run a cold cycle, if possible on “delicate”. Set the spin speed to the lowest setting. If in doubt, do not spin.
Once you’ve finished washing, take your hands out of the bag and dry them on a line dryer, flat if possible. Don’t forget to dry the bag/pillowcase at the same time.
