A few months ago I bought a Microsoft Surface RT on craigslist and it is my favorite piece of technology I have ever owned! I didn't notice until this morning that there is corrosion on my charger. I don't know what to do or think about it. Is there a way for me to just clean it off? should I replace it? is it safe to continue to use? has anyone else had this problem? please fill me in on the what to dos. thank you in advance for any help!
