I make my own laundry soap. I use 1 bar of soap that is grated, 1 cup of Borax and 1 cup of Arm & Hammer Super Washing soda. 1 tablespoon cleans a load, 2 tablespoons for large or soiled loads. I don't use the liquid stuff, too much work. I can grate a bar of soap in 5 minutes, and mix up the rest easily. I prefer to store the powder too, it takes up less room.
I've been using it for years. Works great!
