I have searched for this as well and only found after going through the validation.php class.
I know this post is outdated but for the record... or in case I forget in 2 days
Code:
$this->validation->fullname="";
$this->validation->address="";
$this->validation->email="";
You can do this in your controller on a successfull messages before you do $this->load->view().
