I am kegging my first beer next week (well second beer first kegging). I have no idea how I clean the line. I have one keg and one picnic dispenser. If the keg is in the cold outside or in the fridge, and I leave the dispensing line hooked up, is that OK? I'd assume the beer in the line will be flat and I'd pour a bit and dump that. If I remove the tap line how do I clean that, I'd have to remove the dispensing handle and the quick disconnect to get the tube clean. I feel clueless about this simple stupid matter. Or should I buy a cleaning kit of some sort with a pump?
