We have been using the all natural liquid laundry soap from Costco and have been happy with it. However, I decided to try making my own laundry powder (it is really cost effective). I found a recipe that lists out:
I couldn't find Fels-Naptha at my grocery store, but will be ordering it online, or searching for it locally because I hear it is an excellent stain fighter. However, I also hear it can be caustic, so I've seen the recommendation to use 1/2 Fels-Naptha and 1/2 some other natural soap. I think I will try this with my natural soap being Dr. Bonners.
I also thought the soap to other stuff ratio seemed high, so my recipe is (or will be when I get the Fels-Naptha):
1/2 bar Castille soap
1/2 bar Fels-Naptha
2 Cups washing soda
2 Cups Borax
You shred the soap and mix it with the powder ingredients.
Then, place it is a jar and use about 1 to 2 Tablespoons per load.
I decided to test it out on the hardest washing load I have - dirty cloth diapers. Wow, the diapers came out smelling clean and looking bright. I am a convert. I then did a load of light coloured clothes, and same thing - smelled good and clean.
Can't wait to try it out with my homemade fabric softener (but that is a post for another day).
