Remove and Reinclude Web Pages
Google Webmaster Tool console has been updated (or added to) yet again. This time you can remove content from your page that you don’t want kicking around and have found robots.txt is not successful at eliminating. Conversely, you can also use the new tool in the console to re-include a web page that’s been canned.
For more information on the tool visit the Google Webmasters blog.
