So now I prefer to make powdered soap. It's easy to make and easy to store the finished product and the ingredients up high.
Simply grate one bar of pure soap into a container. I couldn't resist buying a tin container marked as laundry powder when I saw it, but I used to just use an icecream container.
Add a cup of soda/washing crystals.......
Then a cup of borax and stir the ingredients. Couldn't be easier, could it.
I use about 1/2 cup in my front loader. You do need to dissolve it in hot water before pouring it into the machine. I keep a plastic yoghurt container and spoon in my laundry for this purpose.
Now, an observation I have made along the way. If I use a box of bought pure soap flakes, it dissolves beautifully. With my hand grated soap mixture, the soap just softens in the hot water but doesn't dissolve. I still choose the bar of soap though because I get four bars in a small amount of cardboard as compared to much more packaging for the soap flakes. It is also cheaper.
One more point worth mentioning - I did once gum up my washing machine with soap gloop. I had to pull it apart and get the gloop out of the pipes. This can be prevented by occasionally using a hot cycle. So if you washed sheets or similar on a hot wash every month or so, this wouldn't be a problem. Make sure that you don't accidentally put your favourite cardigan in this cycle like I did! I no longer have my lovely cardi!
