I just wash my hands with soap and water before and after.
ps. Are you talking about handling your new snakes? I just got my first ball python as well and was told I should wait at least 2 weeks to handle unless its to clean the cage or maintenance.
Just wanted to make sure you dont stress out our new balls

Yes I am I couldn't resist, I held them for about 5 minutes but they just stayed balled up.
