How to remove an animation clip saved?

I selected my assets to be created to make an animation clip and saved the clip, however I did the wrong positions of my assets and when I create a new clip it still keeps the previous clip that I am saved, I need help to removing this animation clip!

Just find your animation in assets folder and delete it.
Or you can remove that very animation from mecanim, by assigning animation “none” in corresponding state.
Or you can create another animator controller and assign new animations.

If you had details about exact problem would be easier to answer.
