Thanks ! Ya I would not have used soap but I figured rather than having the old beer dry up on the bottom before I could get in there to pick it up I told him to just put a little soap and water on the bottom. I will buy him a small container of pbw for next time.
Thanks for the tip on storing under co2 pressure, I was not even thinking about that......I don't foresee any kegs being empty for too long but I suppose at some point I am going to have one or two that may sit for a while before needed.
Another question if I may...... When I sanitize my kegs just prior to filling I have a hard time getting the star San bubbles out....and then when filling I can't see the beer level, only the bubbles rising and pushing out the top. Any tricks to this? Or maybe I am doing something wrong?
