It is completely possible to wash all tummy pads, valve covers and port covers. These should not fade or damage over time when washed correctly (hand wash, cool water, do not tumble dry, lay flat after washing until completely dry. If you do machine wash place in a protective laundry pouch to prevent accidental damage)
tubie clips can also be washed however it is not recommended as the material used for clips is different and this means that over time they can crack, fade or wear down when washed, however the function of the clip itself will remain the same and will still be functional.
