3-in-1 oil. PB blaster and liquid wrench are more for breaking apart rusted together bolts and pins and stink too much to want to use in your house. You really don't want any kind of spray can for door hinges because door hinges need less than a single drop of oil to be fully lubricated.


I use Shell Rotella 15W40, same as goes in the tractors, same as goes in my Range Rover, same as goes in my mum's Fiat.

In the corollary of the hammer/nail thing, when what you have are 205-litre barrels of Rotella, everything that needs oil gets a dose of it.


What about graphite powder? Isn't that what you put inside the lock, would it work on the hinge too?


It will probably work and as a bonus won't collect dust, the hard part will be getting it actually inside the hinge which might be a bit messy.


Just use lithium grease.
