Has anyone made their own washing up liquid? We are trying to go green (and cheaper) in this house, esp as being pg i am trying to avoid harsh chemicals. I found a book in M&S called Organic at Home where the home section is written by Alison Haynes. There is a recipe for washing up liquid using washing crystals, soap flakes, vinegar and essential oils but unless you want to make 10L it isn't very practical and i had to divde very innacurately by 8 (as i don't have digital scales) to get 1L. And i've ended up with this very watery looking stuff. Does anyone have a better recipe for this and / or any other home made cleaning products?
