Homemade Laundry Detergent: New Tutorial

in Cleaning Products,DIY

Thank you for visiting Little House in the Suburbs. If you like what you see, please check out OUR BOOK.

Homemade laundry detergent, one of the simplest DIY projects, can be really confusing for a first timer, so here’s an updated tutorial.  But first……..

*LIQUID DETERGENT LOSES POTENCY IF NOT KEPT ABSOLUTELY AIR TIGHT*

I just needed to get that off my chest before people start asking me about it.  ANY baking soda, washing soda, or other basic solution (like lye) reacts with air and completely loses potency over time.  In a chemistry lab, these things are kept in liquid form, but only in tightly stoppered little bottles.

So, I no longer make liquid detergent.  Our old liquid detergent post is still popular, but I want to make it clear that it’s obsolete.

No Borax?

Borax is found in commercial LIQUID detergents only.  It’s not very strong compared to washing soda, and requires HOT water to really do it’s thing.  I have omitted it, and am VERY pleased with the results.

However, if you insist on making liquid detergent, PLEASE use borax.  The gelling will help keep it stable for a while longer than washing soda alone.

You will need:

      • 2 cups washing soda
      • 3 bars of soap
      • cheese grater
      • some sort of electric grinder
      • measuring cups
      • scale (optional)
      • an old baby formula container, or the like

 

1. If you have whole bars, use 3- 4oz bars.  If not, you can weigh out 12 oz of random chunks.

2. Grate on a cheese grater.

 

3.  Add the washing soda NOW.  (Soap doesn’t grind well without the dry soda in there to break it up.)

 

4.  Put batches in your grinder and make it tiny.

5.  Use three tablespoons per standard load.  Half that if you have a high efficiency.

Tips and FAQ

      • You do not need a dedicated grinder, bowls, etc.  Just run it through the washer.
      • The finer the grind, the better your dissolving
      • The older and more dried out your soap, the easier it is to grate and grind
      • Borax is unnecessary for powder and absolutely necessary for liquid (if you want it to keep any potency).

David, figure out how many ounces of material you’re using to make your batch; figure out how many ounces are in each tablespoon; figure 3 tablespoons per load (to start) and that will give you an idea how many loads it will do.

What kind of soap do you use to grate?

I’m allergic to ivory soap!! Also I’ve been dealing with a contact dermatitis for years. The only makeup and face care products I can use is Chanel. What would you suggest for a “Miss Itch”like me??

This is a different recipe than what we have been using -which we included in our recently published book on self-sufficiency, homesteading, etc.
How do you like this recipe? Does it clean and remove stains well?

Lucydawn. I use pink Zote for, my daughter had Eczema, and it seems to help.

Please learn to make soap . . . it’s so EASY – really it is!!! You can make it out of all vegan oils, special oils/butters or just using tallow or lard which makes a LOVELY soap – esp. for washing clothes – - – you use a lot more lye in a cleaning soap than you do for a skin product, but it’s super easy and you can make batches that you can make once and use for years before you make another . . . online tutorials are fabulous. But start out with a 1 lb batch no matter what – make it in a trash bag lined box or a “Pringles” can or whatever – since you’re going to be grinding it anyway. Just my 2 cents worth . . . soap made at home is pennies on the dollar and you can know exactly what’s in it . . . the ground soaps now have stuff in it that they do not have to disclose just like foods . . .

Just a couple of questions…
1. How does this powder do in a HE front load machine on cold or warm water? I rarely use hot water to wash clothes.

2. Marilyn, what easy recipe do you use for skin soap and for laundry soap making? I have been frightened of the lye. And I don’t have a scale to measure by weight. Is there a recipe that uses volume measurements instead of weight?

Thanks!!
