I like the idea of lye soap. It is actually much better for your skin. The trick is to use good vegetable based oils. Animal fats tend to be rougher on your skin.
I often wonder what my great, great grandmother used also. I would guess it was her regular soap on a washcloth. I love the idea of making my own things. I like to know what is in my products.
My mother is battling breast cancer right now, so I have taken out all the chemicals in my home. I use natural soaps, shampoos, lotions, and make-up.
I don't think we 'need' detergent based soaps, and I don't think antibacterial is good for us. I did find one website that mentioned a test to make sure all the lye had changed before you use the soap. If the soap isn't acidic enough to use on your skin it is still great for laundry, and dishes (with gloves if you are sensitive). I have been getting my soap at www.bubbleandbee.com. I love her stuff!! I'd love to discuss recipes if you find a good one. I plan to get back to making my own as soon as our move is complete. : )
