It’s pretty easy to make homemade laundry soap, so I’ve includes a basic recipe and a website that has directions with pictures that I like. Let’s start with the ingredients
Homemade Laundry Soap
1/3 bar Fels Naptha, Zote, or basic Ivory
½ cup washing soda (Not baking soda)
½ cup borax powder
You can find all this near the detergent in most stores, even my supermarket had these ingredients. Give the soaps a sniff test, because I love the smell of fels naptha, but my family hates it while it’s being used; they don’t mind the finished, washed smell.
~You will also need a big container – 2 gallon-ish or 3 old detergent containers. I also recommend using a old pot expressly for soap making with its own stirring utensil, grater, and funnel~
Grate the soap and put it in a large pan (remember the soap pan, because you will never get that taste/smell out). Add 6 cups water and heat it until the soap melts, smaller grate – faster melt. Be careful at this point, because it can boil over fast (it will clean your stove, lol). Add the washing soda and the borax and stir until dissolved. Remove from heat. Pour half a gallon of hot water into the container(s). Now add your soap mixture and stir. Now add 1.5 gallon of water and stir. You could do this in separate bottles just ball part it into equal amounts, this is why you might want a funnel and you can use the reused laundry caps to measure for your loads. Let the soap sit for about 24 hours and it will gel. You use ½ cup per load. Make sure to shake before use. Some people like to add a bit of essential oils, but not me. Just be careful to start with a few drops and add it after you try it if you would like more smell.
Here is one pictorial style directions http://www.thefamilyhomestead.com/laundrysoap2.htm There are tons of different, but similar recipes, so look around a bit.
