I have made this wool wash, rather than buying it, and it works brilliantly. It leaves the woollens really soft and smelling lovely, and I also use it when I am wanting to freshen up sheets and doonas etc, and for sterilising these items while they wash. It's also great for towels. I have had this 1st batch for at least 6 months, and I freshened it up a week or so ago by adding some hot water to it, as it hard hardened up and was becoming hard to scoop out. It is now really good again, and should last many more uses before I need to make any more. This is the recipe:
Home Made Wool Wash
200ml methylated spirits
300g lux pure soap flakes or grated laundry soap
100ml eucalyptus oil
Mix all ingredients and store in a wide necked jar.
Use 1- 2 tablespoons per wash. Mix with hot water and then add to warm wash.
