Clean around the moving tip
Match the care instructions to the joints and charging points.
Check the water claim
Read the exact model’s manual for whether it can be wiped, rinsed or submerged. A water rating for one version in a series does not apply to another version.
Look at the seam and moving parts
Follow the maker’s cleaning directions around the tip and housing. Do not pry a part off unless the manual says it is removable. Allow the device to dry as directed before charging.
Check wear before reuse
Look for tears, loose material or exposed seams. Stop using the item if a moving part binds or is damaged, and check with the maker about replacement.
