Erase request from sent by mistake
To delete a demand mistakenly sent out to an individual (e.g. ask for friendship) in the top menu go to "Configuration", then "Privacy settings".
Then write the full name of the individual in the field "Block person".
Then look it up and lock it. So not your friendship demand, will be because blocking someone gets rid of any link with it. If you want this individual to find you or have contact with her, you return to the 'blocked list' and remove it by pushing Erase (however already not your application will appear to him because it was previously blocked).
This does not work for sent messages, given that they are all kept in the Inbox of the person.
Thus the article Delete Facebook from us, hopefully useful thank you.
