POWDER LAUNDRY DETERGENT
I really enjoyed and appreciate your soap calculator. It helped me to create my own own bath soap recipe.
Now I want to learn how to make my own laundry detergent.
Do you have a recipe how to make powder detergent from scratch?
I don't have a recipe for powdered laundry detergent but I do have one for liquid laundry detergent
You could use the handmade soap in that recipe and finely grate it. Then add it in equal parts to borax and washing soda. I haven't done it so you will have to experiment with the quantities to see what works best for you.
