I used this product for "scouring" raw wool fleece as an alternative to the Unicorn product.I love that it has a bit of lanolin in it. My wool washes up clean, soft, and spinnable without the dryness that can sometimes happen with other wool wash products.However, there have been a couple of mohair fleeces that didn't wash up as well. Mohair doesn't really need the lanolin so I wasn't as happy with the feel of the washed fiber. It's okay, and most of it I'll be dyeing anyway.The scent is a bit strong for my liking. It's tea tree oil, and I can really smell it during the washing process. It's not as pronounced once the fleece is dry however. It does smell clean and it might help deter wool moths so that could be a benefit.I haven't priced it out as far as cost of soap per pound of fiber, but because the results are superior, I doubt I'll go back to alternatives like the blue liquid that gets recommended so often.I don't measure carefully when I wash a tub of wool. I toss a sploosh (tm) in, honestly it's probably a cup of liquid to about 10 gallons of hot water (150f), put in wool in handfuls, lots of it, while still leaving enough room for the liquid to move through the fiber. I have a dollar store plunger that I use to push down on the wool to get that soapy liquid moving through, melting and grabbing the lanolin.Oh, and this wool wash doesn't seem to suds up, which is a great thing, suds are tough to rinse out of wool. One of the reasons I never much liked the blue liquid.I'll keep buying this product for raw wool washing. Glad to have an alternative.
