Liquid accidents? One will dry things up (9)
I believe the answer is:
desiccant
'one will dry things up' is the definition.
'liquid accidents?' is the wordplay.
'liquid' indicates an anagram.
'accidents' is an anagram of 'DESICCANT'.
(Other definitions for desiccant that I've seen before include "Dryer" , "drier" , "One takes water" .)
