Other than regular oil, that is. I can't find an old thread where people discussed what they liked to use in their oil squirt can for general household purposes. I recall some interesting responses such as gear oil. I currently use spray lubes such as Tri-Flow, 3 in 1 and a few other sprays, but I find that the sprays are pretty messy, where a squirt can should be more controllable. I'm considering Tri-Flow (expensive!), as it has worked small miracles on a couple of hinges. What is a good all-purpose household lube to use in the oil can? I prefer low or no odor and good availability.
