A few months ago, I tried a fabulous recipe for laundry soap that I found at holyspiritledhomeschooling.net I encourage you to visit her site. It is excellent.
The recipe calls for just three ingredients, plus hot water and a clean 5 gallon bucket, so it is best to do this when young children are not around…perhaps when they are asleep.
Warning: When grated, bar looks similar to shredded cheese, and when melted, it looks similar to lemonade. Don’t let children near it.
Here are the ingredients: 4 cups hot tap water, 1 bar Fels-Naptha, 1 cup Arm & Hammer Super Washing Soda, 1/2 cup Borax (I used 3/4 cup myself). I found all three of these together at my Walmart on the laundry aisle by the stain removal products. Total cost was under $10.00! The two boxes will last for months and you only need a new bar of the Fels-Naptha soap (1.00) for each 10 gallon batch that you make.
Step one: Grate the Fels-Naptha bar and add it to the four cups hot water in a kettle with plenty of room so it won’t bubble over. Stir constantly over med-low heat until soap dissolves completely.
Next step: Fill a 5 gallon bucket 1/2 full of hot tap water. Then I added melted soap, 1 cup of the A&H Super Washing Soda, and 3/4 cup of Borax. Stir it well until all dissolved. It may bubble a little. Fill bucket with more hot water, stir well and cover overnight to thicken, out of sight and reach of children. ( I put mine in the garage) It will gel and separate some.
Next day: You can either follow her directions for diluting it by half again or simply stir the 5 gallon container and use a measuring cup to dip out 1/2 to 3/4 cup (for a full load) into a regular washer while filling it. It will not bubble up, but it works marvelously and smells great. My whole family is happy with it and my allergies have even improved since switching to this, so maybe I was allergic to my old favorite store-bought laundry powder.
I enjoy saving money this way, and so can you!
