Our black soap is definitely a customer favorite. To use, break off a piece and shape with your hands. Work up a soapy lather and enjoy. When you get to the last bit of your bar and it’s too small to use, simply push the old sliver into your new bar and it will unite easily. It is soft and absorbs water easily, so avoid letting it sit in a puddle of water or it will dissolve. Use a soap holder or store in a dry location or in a plastic bag. Extended exposure to the air will cause a thin white film. Don’t worry, this isn’t mold. Your soap still works fine. It is simply the result of water absorption from the air. It can be avoided with proper storage.
