One of the things I do for the environment, and my budget, is make my own laundry soap. It’s really not hard. Here’s how you do it.

This is my favorite recipe that I got from Soaps Gone Buy.
Powdered Laundry Detergent
1 cup grated Fels Naptha Soap
1/2 cup washing soda
1/2 cup 20 mule team borax
Mix and store in airtight container or bag. For light or small loads, use 1 tablespoon. For normal loads, use 2 tablespoons. For heavy loads, use 3 tablespoons.
To make a large batch – grate 6 bars of Fels Naptha Soap and then add 3 cups of Washing Soda and 3 cups of 20 Mule Team Borax. Mix well and store in covered container.
I always make the large batch. Takes 15 minutes and lasts for about 2 months. Using this soap cuts the cost of your load to about .15 cents!
Now, I did recently run into a problem trying to make this up. I was buying my Fels Naptha from a local grocery store. I think the bars must have been sitting in storage for a while because they were dry and very easy to pulverize in my food processor. Then I decided to go ahead and buy a case of soap from Soaps Gone Buy. Their soap is fresh. Now, ordinarily, this wouldn’t be a bad thing, but I found that fresh soap doesn’t break up well in the food processor. I broke 2 little processors trying to grate one bar of soap!
I went out and bought a new, large food processor. It still didn’t break this stuff up! So I emailed the very nice people at Soaps Gone Buy to ask for help. I got a reply telling me to grate the soap, freeze it, then process it with the powders (borax & washing soda) through the food processor. Viola! It worked. She also mentioned that you can cut the bars into chunks, or grate, then just leave them out on a tray under a fan. This will also dry the soap enough to send through the food processor.
Either way, it’s a simple way to help save my budget and the environment.

















Rhea, are there any tips for making laundry soap/detergent for high efficiency washers? these specially formulated he detergents generate less suds, so I was wondering if you stumbled upon a formula for this yet?
