Previously I've lubricated plenty of door hinges by popping out the pin, putting a bit of petroleum jelly, and hammering out back in. This door goes to our garage, tho, and it seems to have different looking hinges.
I'm curious what's the best course of action. Is there a pin that can be easily removed like most interior doors, or do I need to do something different?
That's a spring hinge - I would not attempt to disassemble it. For this one, I'd use a light oil, like 3 in one oil or sewing machine oil and just do my best to get it into the hinge, either through the upper hole with the bar coming out of it, or allowing it to penetrate down the seam in the center of the top. You'll probably need to work the door back and forth a bunch to get the oil where it needs to go.
Like others have said. Silicone spray is magic. Put a paper towel on the ground underneath it, spray the gaps a little, nove the door back and forth. Repeat a few times. Clean the outside afterward by wiping the excess.
I would use a spray lubricant with silicone in it. A Teflon one will work too but Teflon is horrible for the environment so I avoid them. Something like this
I use white lithium grease (spray bottle with thin straw) in the hinges. Maybe you can find a way into the inside with the straw. WD-40 and similar oils are too thin for a hinge long-term.
Nope, I started to look as disassembling, but as another commented said, these are pretty different. That pin it turns out goes all the way through, and the holes on the bottom let me poke all the way through. That means the inside is hollow! Looks like I'll avoid disassembling
