Handmade liquid soap: 1 cup grated soap flakes (5 minutes – don’t even use a whole bar of soap) 10 cups of water (2.5 L) 1 Tablespoon glycerine (you can add essential oils if you want) That’s it. Combine all in a pot, heat til the soap has dissolved and let it cool completely. It will look like it’s not going to set, but forget about it. Leave it overnight and in the morning, LIQUID SOAP! Use a funnel to pour into bottles and enjoy.
