Kitchen scrubber's central bristles need glob (6)

I believe the answer is:

steelo

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

'bristles need glob' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'kitchen scrubber's central' is the wordplay.
'kitchen' becomes 'steel' (I can't explain this - if you can you should believe this answer much more).
'scrubber' becomes 'loofa' (I've seen this in another clue).
'central' says to take the centre.
The middle letter of 'loofa' is 'o'.
'steel'+'o'='STEELO'

Can you help me to learn more?

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