The Futter/O-PEP can be a source of bacterial contamination and should be cleaned after every use. Product information should be followed.
General advice for cleaning:
The device should be dismantled.
Using a bowl with warm soapy water in it all parts should be washed thoroughly.
Rinse all parts of the device.
Place on a lint free dry cloth to dry before next use.
The Flutter/O-PEP can be sterilised (and this encouraged once a week) using the boiling technique or a baby bottle benchtop steriliser/dryer. Do not put the Flutter or O-PEP in the microwave.
