I learned how to make laundry detergent a few years ago. This all came about because:
1). I have a pathological need to try everything I read about on the internet that involves making things that most people purchase.
2). This saves money. Seriously. This detergent costs pennies per load.
3). It cleans just as well as the storebought stuff.
People used to do laundry with bar soap (often homemade) before the advent of powdered detergent. Then liquid detergents came along and the rest is history.
Want to make your own? Here’s how.
Fill a pot with about 4 cups of water. Grate in 1/3 bar Fels Naptha, or 2/3 bar regular soap. Heat until the soap is melted, try not to bring the water to a boil.
Fill your milk jugs almost full with hot water – the 4 cups of water/melted soap will be divided between the jugs, so leave enough room in each jug for an additional 2 cups of liquid. (This is not an exact science. Estimation is fine. It will not blow up or turn into an alien if you don’t use exact measurements.)
Divide the soapy water evenly between the 2 jugs. Divide the borax and washing soda between each. Tightly cap each and shake to dissolve the powders.
Let sit at room temperature overnight and that’s it. You are ready to rumble, my friend. If your soap gels too much and comes out in big blobs, that means too much soap was added. Just shake the jug to break up the blobs and use as usual. Use the same amount of this stuff as you would storebought.
By the way, white vinegar is an amazing fabric softener. And you’re clothes will not come out smelling like a pickle, I promise.
