I've been wanting to make some Laundry Powder for a long time and about a year and a half ago I attempted to make the Liquid Laundry mix. I wasn't that keen on it due to mixing it on the stove to melt the soap, then filling the bucket up with warm water than then trying to negotiate this large amount of liquid into countless bottles and then store them. I found it too difficult and I lost interest. I don't think the soap melted enough at the time and it didn't do it for me. Fast forward to today and I have made some wonderful laundry washing powder.
Recently I came across a recipe for Washing Powder that you used the Thermomix for which is a hands down easy option rather than grating soap by hand. If you don't have a Thermomix it could easily be done in your food processor however I would chop the soap a little finer as these lumps of soap make one hell of a noise when chopping up in the Thermomix.
All the instructions are with the recipe link above and 3 of the 4 items are available at the supermaket. The Borax may or may not be at your supermarket but Bunnings or a hardware should stock it. Handle the Borax and Washing Soda with care and my Thermomix is going in the dishwasher to get a good clean.
It was so easy and I made two batches as the recipe suggested and would have made a third batch had I had another cake of Sard soap on hand. It took me a whole 10-15 minutes from start to finish including taking photos along the way.
I've done my first wash and think this will be great for our little family.
