After use, always rinse your sponge well and allow to dry in an airy place. Be careful not to wring it out as this may damage the delicate plant fibres, just squeeze between your flattened hands. You can also pop your clean sponge in the fridge to keep it fresh and cool, which helps it last even longer. Alternatively, your sponge is happy to be aired on a radiator or heated towel rail. It will shrink and harden when it dries out, this is perfectly natural, simply allow it to absorb water and rehydrate before using again. Never use the sponge when dry. The better care of the sponge, the longer it will last. Never leave the sponge in the shower or in a pool of water. Your Konjac Sponge is a 100% natural vegetable product and should last 1 to 3 months. Once it starts to look tired or breaks down, replace it. Our Konjac Sponges can be safely composted or used in the garden to help water your plants by holding moisture. Never leave a child unattended with a sponge.
