PSA: WD-40 is *not* a lubricant, it's a penetrant.

A penetrant is for helping stuck parts get unstuck. Something like an old bolt that is rusted over and won't turn.

A lubricant is for reducing friction and wear between two sliding surfaces. Something like the plates and pins of a bike chain, or the hinges of a door.

A penetrant is generally a lubricant thinned down with a solvent so it can flow into tight spots. If it smells like a solvent, it's probably not meant for long-term lubrication.
