How can I unlike or get rid of deactivated/deleted Facebook pages I liked?

[Deja]

I've searched all over and i can't find the answer! Facebook says i like 205 pages but I only like 40, and its because theres pages I liked in the past that were deactivated or deleted, but i cant find a way to get rid of those. they don't show up under the "Other pages you like" or anywhere else, please help?

The problem here is Facebook sometimes update some information very slow. That is why, though most of the fan pages you liked are now de-activated, Facebook is still showing the total number.
