Martha Gardeners Wool Wash Recipe. 4 cups soap flakes; 1 cup methylated spirits; 50 mls eucalyptus; Mix 2tbls with hot water to use. Alternatively you can blend it with 4 cups of boiling water and use as a liquid. No need to rinse. (This was so hard to find, my Mum used it when I was little. It came from Martha Gardener's radio show in Melbourne, Australia.) The link is only to her book, couldn't find a page to link to.
