Rust/Corrosion Around Charger Port??

Came into my room to find my light not on on my charger. Wiggled it and it turned back on, but I thought there was no way my charger is already failing (bought this brand new in June) and I noticed some corrosion around my charger/charger port. What is this from? NEVER been wet, by the way. Shame I spent over $2600 and I'm already having problems.

Try cleaning it. https://support.apple.com/HT203207

Lots of things can cause that. Humidity, liquid spill, metallic particles getting stuck to the MagSafe adapter cord end, or on the port for the system. Dust can have metallic particles in it depending on the environment (ie: pencil shavings mixing in with dust.) Any one of those can cause corrosion. Normally there's a plastic coating on the magnetic part, but that can be scratched off by dirt as well on either part.

Worst case, you're looking at having to replace the DC-in board. It's a pretty cheap part, and can be swapped out in under half an hour.

In the future, once the issue has been addressed, try to keep your cable end and MagSafe port clean, or at least visually inspect it more often than you already have.
 
Looks just dirty, and not corrosion at all.
The magsafe connector (the cable end) looks almost gooey/slimey. That end has likely been dipped in some liquid somewhere.
I will guess coffee, from the look of it. (maybe even melted chocolate)
Then, moisture transferred the next time it was attached to your MBPro.
See how the area around the connector pins are smeared? That looks like it transferred from the cable end when you plugged it in.

Try cleaning that goo off with isopropyl alcohol. I have some 91% alcohol that I keep around for just that kind of cleaning.
Dip a cotton swab in alcohol, and have at it.
If it works, you're good! The alcohol won't harm the finish, in any event.
 
I am 100% positive the end of the charger has never been in contact with anything. It stays on my desk away from any liquid or food, as well as my laptop. That is the one thing I make sure of. And you're right, it's not corrosion, but it's definitely some sort of residue. I just noticed that it was extremely hot and it was only plugged in for around 10 minutes, which leads me to believe it is a burn mark of some sort. I just felt the end of the charger taking it out and it nearly burned my fingers, and there is a brown spot on the end of the wire. Faulty charger I assume.........?
 
That is weird, I've clean my magsafe before, just grey residue comes off. I would would call Apple about that, what model year is yours?
 
Well I'm just saying it as I see it I'm a chemist and as far as I'm concerned that is acid damage, how it got there is your problem not mine....
 
That is weird, it does look like some sort of corrosion. You should try cleaning it first but I'm not sure if you'll have any luck getting that off.
 
Does alcohol clean that off?

There's nothing inside the connection, and nothing in the magsafe cable that would leak anything.
Looks like a liquid of some kind, maybe even grease. So, the cable has come into contact with something, and that something was not dry.
