As you can see, most of the stains washed out pretty good. I did not pretreat the stains...just tossed it in the wash. I did wash it by itself with 1/4 cup detergent, so I suppose someone might claim that it is a bit more concentrated because there was no other laundry in the load.
Overall, we are very pleased with the homemade detergent. I might try to use the Fels naptha * next time because I've heard it's excellent for removing stains. I'm excited that the detergent will last FOREVER. I'm guessing about a year based on how much laundry I average and how much detergent I made.
If you want to make powder detergent, WellnessMama also has a recipe for that at the link above.
*I only provided these links so you can see the actual product. I did not purchase my supplies on line--they were available at my local supermarket in the laundry section. Dr. Bronner's castille soap was available in the health food/organic section.
