How to use the alcohol swabs when you get your ears pierced?

I just turned 13 yesterday, which is why I can finally use Yahoo! Answers and got my ears pierced that day as a birthday present. I have gold studs and the man at the jewelry store told me to use rubbing alcohol swabs, and twist my earrings right and left a few times. I am not sure what he meant and have just purchased the alcohol swabs. Please help me with using them!
