Assorted bands continue to clean using fine particles (9)

I believe the answer is:

sandblast

I'm a little stuck... Click here to teach me more about this clue!

'clean using fine particles' is the definition.
I can't judge whether this defines the answer.

'assorted bands continue' is the wordplay.
'assorted' is an anagram indicator.
'continue' becomes 'last' (I've seen this before).
'bands' anagrammed gives 'sandb'.
'sandb'+'last'='SANDBLAST'

'to' acts as a link.

Can you help me to learn more?

(Other definitions for sandblast that I've seen before include "clean building?" , "Clean by using jet of grit" , "Roughen, clean (with jet of fine particles)" , "Clean with abrasive jet" , "cleaning stone" .)

I've seen this clue in the Sydney Morning Herald.
