Use a proper hanger or derailleur alignment gauge pick a spot on the wheel like the valve hole and use that to straighten it if you know what you are doing, otherwise just have a shop do it. The correct tool is not necessarily a cheap tool and the job is one you want to do with accuracy and some knowledge on the topic to not make it worse.
I would not recommend the just bang on it or bend it with other tools "method" as I am sure some one will suggest because it worked for them. Just do it right and then not have to worry.
