Cath makes enough washing powder for a year for under $10. It depends on how much washing you do of course, but I reckon this should last me at least 6 months and that’s a substantial saving!
Instructions to make the washing powder
1 bar soap, grated
1 cup washing soda (Lectric Soda)
1/2 cup borax
Mix together and store in a sealed container.
Use 3 scant teaspoons per load for a top-loader and 1 scant teaspoon per load for a front loader.
You can use up the small slivers of toilet soap you collect if you like, ordinary bath soap or laundry soap. This recipe is ideal for using up all the leftovers you collect in the family bathroom.
It won’t produce masses of suds, but it will get your clothes clean. Suds aren’t necessary to clean but they look good.
If you recycle the water onto your garden (doesn’t everybody?) leave out the borax. Replace it with one cup of bi-carb soda.
