I had a friend down here give me the recipe (and the ingredients) for laundry soap.
She told me the cost for doing it yourself is approximately $3.00 for 5 gallons. What a savings! So, I figured I'd give it a go :)
First I grated a bar of fels-naptha into a pot. (The most time consuming part.)
I added some Borax and some washing soda.
I poured 1 gallon of water into that and cooked on the stove until all the soap melted.
I poured 2 gallons of hot water into a 5 gallon bucket and then poured the mixture from the pan. And stirred.
I added 2 more gallons of water to that and... voila!... laundry soap to last me a long time.
