Reduce, Re-use, Recycle: More on Laundry Soap


I made a batch of laundry soap a couple of days ago that turned out really well. As you know, I’ve been making my own laundry detergent using Fels Naptha Soap. Well, I was out of Fels Naptha soap, and I didn’t want to go to the store, so, I made my own. It’s so easy. I used the hot process method, so it would be ready to use much more quickly.

Here’s what I did:

1 pound of soybean oil (Crisco or non brand name will do)

2.1 oz. lye into 5 oz. water and stir (carefully…remember lye safety!!)

Melt the oil in a crock pot. When it’s melted add the  lye to the oil mixture slowly, stirring carefully, so it doesn’t splash. Once really stirred well, I used a stick blender and blended the oils and lye until trace. Once at trace, I lowered the heat to low and let the mixture cook a bit. (About 15 minutes was all this took.) I added 2 tablespoons of Grapefruit Essential Oils and stirred very well, then glopped the mixture into the mold.

Later that day, I removed the soap from the mold and grated it using a fine hand grater (like what you’d use for Parmesan Cheese) and put the grated soap on wax paper; let stand over night to dry.

The next morning, I mixed 3 cups of Borax and 3 cups of washing soda. I blended it all in my Magic Bullet to make it a really fine powder.

I’m very glad I ran out of the Fels Naptha. I love this stuff!!

I’m linking this post to the following parties! Check them out!

    I am going to try this! I’ve got a friend at work who has some lye (she also makes soaps) and she said she’d give me some to try it out before i go out and buy all the stuff. I’m wondering (and assuming) . . . you must have a special crock pot you use for soap making. I can’t imagine you could use the same one for making soap and for eating. I may scour thrift stores to find an old, working one.

    • I actually do use the same crockpot for food and soap. Because here’s the cool part: everything turns to soap and it just makes the crock pot clean!! The only things that I don’t use in my kitchen are my stick blender (cause there’s no way to get all the soap out of it) and wooden spoons or plastic stuff. My stainless steel and glass stuff I cross use. If you don’t want to do that, there is a Goodwill outlet store on SE 14th behind Applebees and they have some for 99cents. 😉 Let me know how it works!

  2. I’m oh so very lacking in the domestic department. I don’t know any of these words: stick blender, trace, Borax, wax paper. OK, so the last one I know, but the rest.. what are these things? What do they mean? How do I get them/use them?
