Cleaning from New Year's Day to year's end, it all gets scrubbed regularly (10)

I believe the answer is:

janitorial

'cleaning' is the definition.

'new year's day to year's end it all gets scrubbed regularly' is the wordplay.
'new year's day' becomes 'jani' (resembles Jan 1st).
'end' suggests the final letters.
'gets scrubbed regularly' means one should take alternating letters (letters scrubbed out at regular intervals).
The final letter of 'year' is 'r'.
'it'+'all'='itall'
The alternating letters of 'itall' are 'ial'.
'jani'+'to'+'r'+'ial'='JANITORIAL'

'from' acts as a link.

I've seen this clue in The Telegraph.
