Cleaning my belly piercing?

Okay, so 5 days ago I pierced my belly on. I know I should have gotten it done professionally, but I didn't so please don't gripe at me about how dumb I am because I did it at home. Anyways it isn't infected and I think it's doing pretty good but I don't know how to clean it. Two of my friends got theirs done professionally, 1 of their piercers told them to clean it with hydrogen peroxide, and the other piercer said to use antibacterial soap. So far I have used both of them, but what is the most proper way to really clean your belly piercing?
