Homemade Laundry Detergent….IN THE MICROWAVE!!!

I often joke with my husband about being born in the wrong century.  I love doing things the old-fashioned way, but about the time I am convinced of this I realize that I am incredibly dependent on my modern-day conveniences….like the Microwave.

This fact was quite evident a while back when I made my first batch of homemade laundry detergent.  It worked terrific, but I hated sitting over a pot for 45 minutes melting soap and waiting for the ingredients to dissolve.  So pioneer woman meets modern gal in this little recipe…


It almost seems wrong.

I got the original recipe here  and modified it to be done in the microwave.

Here is what you will need:


1 bar soap  (Fels Naptha, Castile, or Ivory)

1 cup Borax

1 cup Washing Soda

4 cups water

About 3 days before you are going to make the detergent, turn your bar of soap into liquid. (In this recipe I used a 4 ounce bar of Kirk’s Castile soap.)

Pour your liquified soap into a microwave safe dish.  It should be about 2 cups of soap.  Add two cups of water and stir together.


Microwave on HIGH for 2 minutes.


After two minutes, the soap and water should mix together well.  Set aside.

photo(104) photo(103)Place the lid on each jar, and shake for about 20 seconds.  Place the jars upside down and let sit for 4-6 hours.  Do not let them sit longer than this, if you do your detergent will become grainy.

photo(120) photo(121)Unscrew the lid to the jar, and screw on the blade for the blender.  Place it on top of the blender and mix on high until it becomes creamy.  Your jar will be completely full at this point.


When you pull the blender off, it will be thick like this.  It is about the consistency of mayonnaise.


Repeat with each jar replacing the lids tightly.  This detergent is highly concentrated.  You will use ONLY 1 Tablespoon per load.  Don’t use too much!!!

Here is a list of reasons why this is my FAVORITE homemade detergent:

1.  I didn’t have to stir and stir….and stir over the stove waiting for my soap to melt.

2.  No grating soap.

3.  It doesn’t take up much space and lasts forever.

4.  It cleans my clothes GREAT!

5.  It dissolves almost instantly when you put it in the machine.

6.  It is just cool…….  🙂

If only I could learn to enjoy washing the laundry as much as I enjoyed making the detergent……

    Can you add essential oils for fragrance? Or liquid fabric softener to the load?
