I don't think I've even heard of anyone lubricating their garage door
wire ropes. Typically, they're lubricated to protect the ropes, not
the sheaves of blocks. There's lots of friction inside a rope, as the
various fibers are forced to move past each other, and there are
corrosion problems with steel ropes. lubricant is typically a bunch
of oils in a solvent. Solvent allows the oil to get where it's
supposed to get, and then evaporates, leaving it there. A real
hardware store, or a farm store, or a crane supplier will have
something suitable.
