And another one, for the bike. Triflow. The small squeeze bottle. Put it in a ziplock bag. The stuff flows incredibly well! For chains, derailleurs, brakes and everything else that moves. Yes, there are better lubricants for each purpose, but Triflow does to all, quite well. (And while your drivetrain will go to filthy black - hence the hence the Bronners - Triflow is not a gunk magnet.) Just remember to shake well before application otherwise you are just using a very light oil that evaporates off. I re-shake mid-way for chain lubes.
