Bend in wire can be tidied up (9)

'tidied up' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives can occasionally mean the same thing.

'bend in wire' is the wordplay.
'bend' becomes 'lean' (leaning is a kind of bending).
'in' means one lot of letters goes inside another.
'wire' becomes 'cable' (cable is a kind of wire).
'lean' inserted into 'cable' is 'CLEANABLE'.

'can be' acts as a link.
