I use it for all my newly handspun yarn -just takes a drop or two and let it soak for about 15 min. It cleans and deodorizes as well-it's fabulous stuff. I've had a bottle of it for over a year and it'll probably last another. I'll also be using it to wash Tom's kilt hose. I buy online and wish I could find it locally, but it's worth whatever it costs-a whole lot better than Woolite (ugh!)
