I was just reading about a woman who did this and was wondering about the recipe. Thanks! Is the Castille soap and washing soda something you can get at a WalMart? I’ve never seen it before.
You should be able to get them at Walmart or even grocery stores, both are very old products.
Check in the laundry/cleaning sections, the soap might turn up near shampoo, or with the bars of soap.
I have been reading these soap recipes 10 years or longer and the people who use them, like them.
As I understand it, start with about a quarter or even less of what you are using now.
