Means to wipe material linked with online pest (6,4)
I believe the answer is:
toilet roll
'means to wipe' is the definition.
I can't judge whether this defines the answer.
'material linked with online pest' is the wordplay.
'material' becomes 'toile' (type of fabric).
'linked with' means one lot of letters go next to another.
'online pest' becomes 'troll' (annoying or provocative internet user).
'toile'+'troll'='TOILET-ROLL'
Can you help me to learn more?
(Other definitions for toilet roll that I've seen before include "Loo tissue" , "feature of the smallest room" , "extensive quantity of paper" , "long paper" , "Tissue paper" .)
