So I just got 2 corny kegs and 5 lb co2 tank from a friend and a couple of lines. 1 is a line for what looks to be for co2, the other line is for transfer between kegs. The lines have been sitting around for I don't know how many years in the person's basement and are some kind of braided material. Do I need to replace the lines, or can I give them a good cleaning? Also the clamps on the braids are a bit rusty.
