Please note that the following instructions only refer to products made entirely out of silicone and do not refer to products containing any other materials. The cleaning methods may not be suitable for non-silicone products. To clean silicone, just give them a good scrub in hot soapy water and then rinse. Pat the outside dry and leave to air dry on a drying rack. BUT, if you are in a rush to re-use them, just pop them in the microwave for 2-4 minutes (stopping them halfway to turn them over) and they'll come out completely dry! The Haakaa Double Ended Silicone Brush is super handy when it comes to cleaning silicone items. It's soft silicone bristles easily remove leftover food and milk without scratching silicone surfaces.
