The Philips AVENT 3-in-1 Electric Steam Sterilizer SCF284/05 uses natural steam to kill 99.9% of germs and bacteria in just 6 minutes. Before sterilizing, wash items in warm, soapy water or the dishwasher. When they're clean, place them in the sterilizer. Fill the sterilizer basin with 100ml of water. Plug the sterilizer in to any standard electrical outlet and switch on. The sterilizing cycle will run for 6 minutes and then the sterilizer will automatically shut off for energy savings and safety.
