Gas line has plastic smell. Should I clean it before first use?

Setting up my first kegerator, and the CO2 lines smell pretty bad (plastic/glue/toxic yuck). Should I clean these out? PBW? Boil?

Just clarifying this question is about the gas lines, not the beer lines (I plan to clean those).

Running sanitizer through them sure wouldn't hurt
