Corroded Neutral into Service Box
This is a short question for a long answer. I am going to assume that you live in a mobile home or manufactured housing unit that has aluminum wiring in it. And what you are experiencing is the eventual deterioration of that type of system. 

You need to inspect and repair all of the wiring termination, starting from you panel and continue all the way to your last outlet. If you do not feel you have the experience to complete the task yourself I would advise you find a trusted contractor and employee them to do it.  

I am sorry to deliver the bad news but your situation requires immediate inspection and repair to prevent further damage to your system. It may be at an expense you were not prepared but I feel it must be dealt with. 

Sorry to deliver the bad news. I wish you the best of luck.
