So instead of the dreaded grating, we used the microwave to do the work for us. After the soap cooled down I flaked it and added it to the other ingredients for our homemade soap. Not only was it fun for the kids to watch, it also cut the prep time in half...thus making this homemade soap even cheaper as my time is definitely worth something to me! Have fun!
Homemade Laundry Soap - Basic recipe
2 cups Borax
2 cups washing soda
2 bars of soap (I prefer Ivory as that's what I grew up on)
1 lidded container. Plastic or glass, whichever works best in your laundry room.
(If a heavy duty soap is desired substitute the soap with 2 bars of Fels-Naptha. But did you know you can just rub the bar directly onto a stain? Personally I do not think it's the best stain remover but I have tried it and it works on light stains. It did not work on grease or grass. But it is commonly added to homemade laundry soap, thus the mention.)
Add Borax and washing soda to a container. Place one bar of unwrapped soap onto a microwave safe plate. Microwave for 30 seconds. Continue to heat in 30 second intervals until the soap has fully "melted". Remove carefully as the soap will be VERY hot.
Let it cool completely, then flake apart. Continue with second bar.
Add flaked soap to the container of Borax and washing soda. I have a front load washing machine and use 1/4 cup of this soap for each large load. I have found homemade laundry detergent works best with warm and hot water settings. For cold water settings I still use liquid Ivory Snow.
