Did you know that loofah is a plant? The namesake of plastic shower scrubbers, loofah (or luffah) is a gourd-like plant. The dry loofah is the 'skeleton' of the fruit and is harvested once the plant is dried. Hang to dry your loofah after each use. To keep clean, the loofah can be boiled for a few minutes. Dispose in the compost at the end of its life.
