- Add the water to the mason jar, just regular water from the tap is fine. Add the Bronners Castile Soap.
- Add the (completely powdered, LUMP FREE) arm & hammer washing soda, a little at a time, giving it a chance to dissolve, or it will overflow causing a Mess. Do not use baking soda, it will NOT work. Put the lid on the jar, make sure that it is seated properly so it won’t leak and screw the band on tightly. Shake vigorously to blend all of the ingredients well.
- INVERT THE JAR. DO NOT SKIP THIS STEP or you will have a solid block at the bottom of your jar that you CANNOT get out and be sure to Follow the directions COMPLETELY. DO NOT LEAVE THIS OVERNIGHT, it must be whipped during the time frame stated or it will turn into a solid chunk which WILL Break your Jar.
- Leave it alone for at least an hour, then shake vigorously again. Put it back & make sure it is still INVERTED. You DO NOT want the contents to settle on the bottom of the glass jar.
- After a couple hours or so, open the jar and it should be gelled
- Attach your blender blade and gasket right to the mason jar, (we use a cheap oster blender for this), and whip for a minute or so until all the ingredients are well blended and smooth and creamy.
- For those with Normal Water: Use 1 Tablespoon per Load of Dishes. This is a very low sudsing homemade Dishwasher Detergent.
- For those with SOFT Water: Use 2 teaspoons ONLY per Load.
Author Notes
While several of our other dish washing soap recipes call for Borax, You’ll notice that this recipe doesn’t. Many of our website guests and members were leery about using Borax on their dishes, for fear that it wouldn’t wash away completely or that it was leaving frosty/cloudy dishes in the their dishwasher. If you prefer a dry detergent, there are links to those dishwasher recipes at the bottom of this page.
While this recipe is pretty simple and doesn’t require cooking of any kind, it does require that you follow the directions completely, or it won’t come out properly. (Trust me, I made 13 batches of homemade dishwashing soaps before I finally perfected this one. So, take advantage of my willingness to trash my own kitchen in the name of DIY & MYO!)
