DO NOT USE WD-40 or other Penetrating Oil !!
I've used Blaster White Lithium Grease (or any other W.L.G).
Use a small "drop cloth" behind the hinges to capture the excess spray.
I always open the door all the way, spray a little, then move the door to the next bump , spray a little more.
Then do the opposite ... open door a little at a time, spray, open a bit more, etc.
Then move the door open to closed to open a few times to ensure the grease works all around.
If you find the spray with a built-in "thin spray straw", get it.
Otherwise, be sure the lube you get does have a straw scotch-taped on that you can snap on the nozzle.

Alternatively, you could skip the spray can and get a small jar/can/tube of white lithium grease and apply it with a little acid/solder brush. May be less messy and provide heavier duty (thicker) lubrication.

The problem is you need to get it inside, to the pin. Spray and pray, I guess...
My W126 had grease fittings. Many older cars had a slot milled in the pin that extended up through the head. a couple of drops of oil and all was good.
I just figured since it's listed as a maintenance item, there would be a procedure.

If it’s really creaky, you might have to start with a little bit of penetrating fluid. Kroil, Krown, or CRC are pretty good. You may need to put a rag on the rocker panel to catch any drips. Exercise it in and then follow up with lithium grease. Spray the hinges every oil change with the grease. Don’t forget the gas door.

I made my own non staining version from a mixture of about 4 parts white mineral oil to 1 part oil of wintergreen. I put it on the pins with a dropper as needed. I made about a pint of it years ago and still have it.

It must smell wonderful too. No need for a stinky little tree hanging from the mirror.

I don’t exactly remember what the GLK hinges looked like because it’s been gone 5-6 years. I just use a pointed end dropper and put a drop or two anywhere the hinge pieces rub and at the top edge of the hinge pins. I also put it on the piece that has the intermediate door stops. I work the door for a minute to get the oil to work its way in, too. Then I add another drop or so as needed. Got the mineral oil from a pharmacy and the wintergreen from a nutrition store when I had my ‘03 W211.
All but one if the cars parks indoors at night and at work, so ours may not see as much abuse from the environment.
