Laundry Detergent Recipe


As a family of six, we do a lot of laundry around here.  At any given moment I’ve got a load in the washer, or at least I should if I don’t want to get behind.  And the cost of all the laundry detergent starts to add up, especially the dye-free, fragrance-free, most scary-chemical-free brands that I favor.

So a few years ago I started to make my own.  It sounds hippie and a bit crazy, but really, it takes very little time and saves so much money.  Plus, it’s free of the dyes, fragrances and chemicals that I want to avoid.


1 cup Washing Soda (NOT baking soda, it’s found in the laundry aisle)

1 cup Borax

1 cup powdered Oxi-clean (optional…I find my colors and whites are brighter with the oxi-clean than without)

1 bar Castille soap, grated (you can substitute Ivory soap, or Fels-Naptha if you prefer.  I like unscented castille best based solely on smell, not effectiveness)***


Mix all ingredients together and store in air-tight container.

Use 1-2 tablespoons per load, adding to washing machine per your machine’s instructions.  You may have to use more or less depending on your water, washing machine, dirty clothes, etc.

I can’t find my cost analysis (yes, I made a spreadsheet.  I’m a geek like that) but believe me when I say it saves money.  A lot of money.

I make a big batch (usually 4x the recipe) and keep it in an air-tight container in the garage…..I keep a smaller container of it with a measuring spoon in the laundry room.    It lasts me 4-6 months, depending on how much laundry I have in that time frame.  I tend to use more in the winter than summer, though now that we’re the new house with lots more outside chores and activities, that may change.

One more thing, I find grating the bars of soap a bit tedious, though it still only takes maybe 10 minutes for 4 bars.  I used to use my box grater, but my knuckles were taking a beating with that method.  Now I slice the bars into several slices, then give the slices a rough chop.


Then I throw it all in my food processor with the chopping blade to make a finer powder.  My food processor best chops about 2 bars at a time without gumming up too much or overheating.  Short pulses are better than a continuous run.



If you search online for laundry detergent recipes you will find hundreds of variations….this is the one that works for me.
