My friend Corrie gave me a recipe she uses but if you were to do a google search, you'll find many variations on the recipe.
It took some work & elbow grease... but I found the most difficult product. Fels-Naptha!
Just $ .97 at WalMart
Borax $ 3.79
Washing Soda $ 2.99
That's a total of $ 7.75 for about 6 cups of detergent. About 16 tablespoons per cup, 1 Tbsp for a regular load, 2 Tbsp for a heavy load.
That means about 96 loads (regular) means $ .08 per load.
Dry Laundry detergent:
1 bar Fels-Naptha Laundry soap
2 cups Washing soda
2 cups Borax
Grate the Fels-Naptha with a cheese grater. I used the small grate side because I wanted the mixture to mix well. Also, when you do the laundry, you only use 1-2 table spoons, its harder to measure when there is big hunks of soap.
Mix all ingredients together.
Next time I would try my food processor's grater. It was a lot of work and took over an hour to grate the bar of soap., but I'm happy with this and can't wait to do laundry!
