The soapwort soap worked a treat! I did end up putting 4+ capfuls in, not three.
Even in these enlightened times I find it hard to fathom that something is cleaning something without trillions of bubbles, I’m getting there though!
I probably wouldn’t use it to wash really dirty clothes but use one of Wendyl Nissens’ recipes. Go here for some of her recipes for natural cleaning products.
For the recipe I used to make the soapwort liquid soap see my post here.
