Cleaning between uses: It's recommended that you disassemble parts, soak with soap and water for 15 min and let air dry before reassembling (suggests using distilled water to prevent mineral buildup- but i don't do this)
Sterilize once a day by first disassembling parts, cleaning with soap and water, and then using a electronic steam sterilizer, like the WABI, or boiling for 10 min (again recommends distilled water, but I use tap). When boiling, it's recommended that you place a rack on the bottom of the pot to prevent plastic parts from coming in contact with the hot bottom. Let air dry thoroughly before reassembling.
