How to delete "liked" pages on facebook?

[PSRC]

Go to your profile
Scroll down until you see the Like Pages or something...
Then click the pages you want to unlike (if it is a page outside facebook, you need to delete it through the about me section)

Then click unlike button when you scroll down the page *fan page*

Go to your profile, Info, Likes and interests and go to edit and from there you can get rid of all the pages you don't want. That's the easiest way I find to get rid of liked pages. after you done deleting all the pages you don't want, click on save changes. Hope this helps
