a post on the blog Thy Hand Hath Provided on how to make your own liquid laundry soap. I very much liked that idea. It's easy, cheap, and chemical free. I love projects that are kind to the environment as well as my wallet.
I bought a bar of Fels-Naptha soap, a box of borax, and a box of washing soda and set out to make my first batch. Easy as pie. A little grating, a little stirring, and some patience was all it took to end up with five concentrated gallons of detergent. A lot of people seem to prefer powdered detergent but since my washer and dryer are located in a rather damp basement, that is not an option for us. I added about twenty drops of lavender essential oil to make it smell nice(r).
So far, I am really happy with my soap. It works great. I use the same amount of detergent per load as I always have. The only thing I changed in my laundry routine is that I have started to add about 1/3 of a cup of borax to every load. We have very hard water and borax is said to help with softer water, nicer smelling laundry and better stain removal. It seems to do the trick.
Depending on the size of your dryer and the load of laundry, you need about three to six balls. If you have an extra large capacity dryer like I do, you might want to throw in a few more. The dryer balls will last you for many, many years. And all that time you're saving money on fabric softener and/or dryer sheets. And the planet thanks you, too.
