I keep coming across this recipe for a home-made wool wash. Once I get the $$ together for the ingredients, I'm going to give it a try (and I'm going to add some liquid lanolin to it myself, though it's not in the recipe).
I don't know where it originated, or even what site I got this recipe off of - I have it saved on Notepad. 1 cup methylated spirits (note - also known as denatured alcohol -ethyl alcohol denatured with a small amount of methyl alcohol)
4 cups pure soap flakes
1 small bottle eucalyptus oil.
Mix well together, it's rather thick and gluggy. Use one tablespoon of mixture to a bowl of water.
