Recycled Soap Slivers. Collect all leftover soap slivers and grate them on the grater. Any colour is fine. Put them in a bowl, added a little water, and mash them all together. Form a whole new bar with the shavings and let them dry a few days before using them again. Saves heaps. I make my own soap for allergy reasons and I always have little leftover bits – these makes the oily rag go even further!
