• You Will Need:
  • Ivory Soap
  • Microwave

Today I used my microwave to make another batch of my homemade powdered laundry soap.

What ?? Why would I be using the microwave ??

It turns out the microwave can be an interesting method to replace the “grating of the Ivory soap” process. And if you’ve ever made a batch of homemade laundry soap, then you know the grating of the soap is the most tedious and boring part of making the mixture.

My usual method is to use my little hand grater that I bought at the dollar store and sit in front of the TV while I spend the 10 minutes or so it takes me to grate a couple bars of soap. And yes, sometimes my arm gets a little tired.

*Please don’t think I’m a wimp*

Some of my helpful readers shared with me that there are folks out there who microwave their bars of Ivory soap as a clever, fun (and kind of goofy) way to eliminate the grating.   Microwaving a bar of Ivory soap is really more of a fun science experiment and you can find plenty of YouTube videos of people fooling around and giving it a try.  It will puff way up and turn into a Ivory soap cloud that when removed from the microwave will simply crumble apart.  Any other bar of soap will melt in the microwave.

NOW, if you’re making homemade laundry soap with a bar of Ivory, this little trick can be quite helpful.  Instead of spending your time and energy with a grater, you simply crumble up your dry puffy microwaved Ivory soap.  If you whirr the crumbly bits around in your food processor too, you get a nice powdery consistency which is perfect for homemade laundry soap.

REMEMBER – this will only work with Ivory bar soap.   A bar of Fels Naptha soap, or any other soap, will simply melt if microwaved.

Remove your puffed up Ivory cloud from the microwave  (let it cool if necessary) and then break it into pieces with your hands.  Place the crumbled dry pieces in a food processor and process for a few seconds until powdery.


And here again is my favorite homemade powdered laundry soap recipe that’s a perfect way to put your microwaved bar of Ivory soap to good use.
