I love doing things like making my own laundry detergent. It's quick, easy, economical, and it works great. What's not to like?
3 ingredients plus one more for rinse cycle:
1 bar of Fels Naptha soap, grated, grated the way you'd grate a potato
1 cup of Borax
1 cup of Washing Soda
Add white vinegar at rinse cycle.
A lady who lives in my apartment was a minister's wife and knew how to economize and to feel good about what she was doing. She gave me this formula. She said this costs about 4 cents a load.
Not only that, in my experience, this gets clothes as clean as any other laundry detergent.
Sorry, detergent companies, you're going out of business!
P.S. That reminds me. I used to use Ivory Flakes when my daughter was little. I liked it very much. I believed it was 99.9% pure. Where are ivory Flakes now?
