when I was a kid, my mom used to save all those slivers of bar soap and when we ran out of laundry detergent, one of us kids would be assigned to pare the soap bar slivers into the washing machine with a potato peeler. It was an old wringer washing machine. Sure, don't know how it would work in a modern machine. My grandmother regularly used Fels naphtha laundry bar soap and would shave that into the washer, I don't remember if she added anything else.
