The magnet can collect very small metal debris. You might get a magnifying glass and check the plug and port for metal stuck to it. If you don't find anything and the problem persists, don't risk your MacBook. It's better to get a new one or take what you have to Apple and let them check it out. What did you clean it with? 91% isopropyl alcohol should be acceptable.

Regarding "... better to get a new one." I mean it's better to get a new charger than to risk your Macbook.

With the magsafe adapter still staying green after being unplugged from the wall, I have to ask, are you using the original charger that came with the computer or a official apple magsafe charger, or are you using a unbranded or third party charger?
