So, here’s what I tried…I got all the ‘ingredients’ from plain old Safeway supermarket. I always have good intentions to go to a local organic grocer or co-op but I work 9-5 like many and a 80 minute commute each way means I have limited access to organic type shops. Borax (sodium borate) seems to be a contentious ingredient . Some recipes mentioned Borax, others said, no, no it will kill your plants and garden worms. So I went without for this recipe. In general, I use borax for washing really smelly towels and sneakers as I’ve tried nothing else works as well. It can be added to your washing water but personally I limited it to grey water which goes on hardier non-edible pot plants.
I got my recipe from this wonderful blog Towards Sustainability.
2 cups washing soda**:
4 cups grated pure soap (e.g. Sunlight soap) or Lux Flakes:
I also added some tea tree oil Mix all ingredients together well, and store in a plastic container with a lid. Use 2 tablespoons per wash.
* Borax is a naturally occurring mineral (sodium borate) but too much on your garden is toxic to plants and worms, so if you are going to use your grey water on your garden, leave out the Borax.
