How do I clean corrosion off of my mobile phone charging port?

How do you clean corrosion or dirt/gunk off of your charging port on your mobile phone? 

The best way to do this is with a tooth brush and alcohol.  Take some, not a lot, of alcohol on the end of a toothbrush and rub it against the port.  This will generaly remove most surface damage or corrosion.  Of course if their is a burnt spot or more serious damage on your phone, this will not be able to remove that.  Also if you able to take your phone apart.  This is good for cleaning the inside of your phone if you have had liquid damage to the internal components.
