Iris Hantverk kitchen sponge 2-pack from Iris Hantverk is a natural, sustainable cleaning sponge made from 100% loofah. The loofah is plant-based, organically grown and processed without chemicals, giving an effective yet gentle sponge that won’t scratch surfaces. Wet the sponge for a softer texture and use it for dishes and general household cleaning. Lifespan is about 4–6 months depending on use. Clean by boiling in water with mild dish soap, air dry and store preferably on the hanger. When it becomes too soft or discolored it can be composted.
