Ok, so I kicked a keg and it won't be used for a few weeks. What is the proper way to store that line/tap? It was only in use for about 5 days so no chance for buildup of anything. I flushed the line and tap with just water to push the beer out and rinse it all. Should I put PBW or StarSan in the line for storage? I didn't disassemble the tap.. just flushed.
