How do I sanitize the parts? Are all the parts dishwasher safe?

              Use a bottle brush, one with a smaller brush on the opposite end, to reach all the tiny nooks of the pump parts.

              Rinse each piece thoroughly with hot water for 1O to 15 seconds.

              Boiling is not necessary as long as you have rinsed the parts with hot water for 10 to 15 seconds.

              You may choose to sterilize these parts by boiling but not more than 3 minutes. Exposure to heat through boiling will cause damage to the plastic, silicone and membrane.

              All parts may also be washed in the dishwasher using the top rack except for the valve and membrane.

              After washing, lay all the parts on a clean paper towel or on a drying rack and allow all parts to air dry.

              Make sure all the parts including valve and membrane are dry prior to use.
