The materials used in the production of your MistyClip mean that it is environmentally friendly, but special care is needed to ensure it lasts for a good long time. You should only ever clean your MistyClip in warm (but not hot!) soapy water.
Warning: hot water or excessive heat will cause your MistyClip to change shape! And never use chemical cleaners, otherwise it might not just be the mist that disappears!
