Forum:SH:Cleanup

I'm sorry if this is a question easily answered elsewhere; I've been searching, but I could not find a definitive answer. In regards to pages needing cleanup, when is it safe to remove the cleanup template? Is there a particular criteria that needs to be met per page, and would it potentially be useful to post on a page's talk section what about the article requires being cleaned?
