Last year I wrote about making Laundry Liquid. This Laundry Powder works just as well as the liquid.
To make this you will need:
- 1 cup washing soda
- 1 cup borax (see below)
- 1 bar grated castile soap
- food processor or blender
Place the grated soap, washing soda and borax into a food processor or blender and blitz until you have a reasonably fine powder with no lumps. This can be a bit noisy at first until the washing soda crystals have broken down.
Store in an airtight container. You need 1 heaped tablespoon for a standard wash or two for a really dirty load.
This seems to work equally well in a cold or warm wash. I've found the laundry liquid better for washing woollens.
Note on borax: Borax (sodium borate) is a naturally occurring alkaline salt that helps lift dirt. It is not the same as boric acid.
