Q-tip, for example (4)
I believe the answer is:
swab
'q-tip for example' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for swab that I've seen before include "Mop; surgical pad" , "Absorbent surgical pad" , "Mop up - uncouth fellow" , "Hospital cleaner" , "Among others, Q-tip" .)
