So I have MacBook Pro 13" 2015 and when I connect the MagSafe power connector to it, it seems like it’s more difficult to charge. So I check the MagSafe port and want to clean it I think.
When I checked charge port I think it got corroded, or I don't know what it is, but I think it isn’t burnt. So I'm afraid to charge the MacBook, and I do some first aid to try to clean it with cotton swab with alcohol but it shows nothing.
But what should I do? Is this safe? Should I just continue to use it and charge it? Or should I bring it to an Apple Authorized Service shop or just any common non-Apple service center?
