Wordpress: Restoring a theme to it's default settings

So I installed the "twenty fourteen" theme for my Wordpress website, and I want to change it to it's deault settings. With this I mean resetting the theme to how it was when first installed (with no modifications). Currently I have checked the database to check if I could restore the wp-options theme value to default, but that item on the database does not exist. I also tried changing themes, deleting twenty "fourteen" and installing again from wordpress and still no luck. Any ideas?
