Just bought a Mark II keg and carboy washer. It was a suggestion by a friend who loves his. Most info I see shows cleaning with PBW which is something I always do. But with the keg cleaner and using PBW it doesn't show rinsing. I have always thought that you need to rinse the PBW off kegs etc. after you clean them. So do I just empty the washer and rinse it so I can put clean water into it for rinsing a keg or just take it to the faucet and rinse it?
