Having made more laundry detergent from this recipe, using home made soap as the main ingredient is beyond compare. Just because people online say it's a good use of leftover bar soap, doesn't mean much until you actually try it, and I have. Home made soap is much better for laundry detergent, I would even put it up over fels-naptha. though fels has a better smell. Also, this last batch,I used more soap and borax than the recipe calls for (about 10% more) and feel it is well worth the additional cost. This batch was made with castille soap.
