How long google takes to remove 301 redirected urls

[fsmobilez]

Hi

I have canonical issue with google search as my site was crawled with
www and non-www

so i added permanent 301 redirect also set preffered domain as www in
google wmt but still after threee months google is not removing my
urls when i click on cached its showing nothing but problem is why
google is not removing my site urls

The site was dynamic site and i add 301 redirects for some strings and
google not removing that urls as well , although no cache for that
pages as well.

Will google remove my urls or not.

What google is doing with me.

Plz help me.

Google has a long memory for urls - so don't worry about WMT reports so much. It takes a while to get that straightened out.

What you really need to notice is the search results. If Google is still showing the old urls for searches and sending traffic to them, then I would look closely at your 301 set-up for technical problems. But if the public search results are straightened out, then you have no worries about WMT - it's a reporting function and only for the site owner.
