Made to look old, nothing modern getting stored round about (11)

Ross

I believe the answer is:

stonewashed

'made to look old' is the definition.
(stonewashing makes things look old and faded)

'nothing modern getting stored round about' is the wordplay.
I cannot quite understand how this works, but
'nothing' could be 'o' (looks like zero - 0) and 'o' is located in the answer.
'modern' could be 'new' (synonyms) and 'new' is found within the answer.
'stored' could be 'stashed' (I've seen this before) and 'stashed' is found in the remaining letters.
No letters remain.
This explanation may well be incorrect...

I've seen this clue in The Times.
