★ Can be washed with hot, soapy water. But do not wash mold with abrasive pads or cleaning agents like Ajax cleanser.

★ Tips on clay: Since different clays have different features, there are clays which are sticky and softer than the others and so affect the pop out effect, in this case, we recommend you to put the mold (with the clay inside) into the fridge for around 5-10 minutes before you pop the clay out.
