Can't clear email addresses from web clipper on public computer.

[mls 0]

I am a school librarian and have just started using Evernote with my students. A couple of students mistakenly saved their emails and passwords on our school computers. I'm using chrome so I went into the chrome settings and disabled all of the auto fill functions. I restarted the machines but the email and password still appears. Webclipper also saves the email of the last person who used it. What do I have to do to clear this information and prevent it from being saved in the future?
