So I was looking around on the blogs and I found a great recipe for homemade powder laundry detergent at Evening Shade Morning Latte. When I went to make the detergent I didn't have all the same ingredients so I had to make some substitutions and I was very pleased with the results.
Here is what I used:
3 pk Ivory soap, 12 oz total
4 C Borax
2 C Washing soda
2 C Baking soda
I used a hand grater for the soap and then put it into the food processor to chop it up very fine.
Note: You could use the grater blade on the food processor but mine is missing for the "old" processor that I use for crafts and stuff like this, so I just did it by hand.
I slowly mixed in the borax, washing soda, and baking soda until everything was mixed well. For normal laundry I used 1-2 tablespoons. I love this recipe, the Ivory soap makes it smell great and the the baking soda also helps freshen it all up. The clothes are also VERY soft.
I keep it in an air tight plastic storage container.
