Perhaps a sign reading “Please leave door open.”
Or a degreaser.
You put a powerful fan in front of the door and the door closes if you aim the fan right.
The door closes spontaneously when left to itself. I doubt the sign will change its uncooperative attitude. It is not unlike my patients that way.
The fan plays hell with my paperwork, and also knocks my inspirational posters (placed to motivate my patients) off the walls. 
No, I guess I’ll have to just wait for maintenance if my one patient’s breath doesn’t add grit and other fine particulate matter to the grease.
I can’t think of a one-word antonym, but grip improver would be the general idea - like gymnast’s chalk.
I don’t think dessicant is right, as not all lubricants are wet.
For the specific problem of hinges you wish you’d never oiled, I reckon a little talc might do the trick - and it shouldn’t be abrasive enough to actually wear away the hinges.
Loctite?
That might not be a bad idea. Something to gunk up the oil, and make it more thick. A really fine talcum? Try and sprinkle or puff baby powder into those hinges?
Win.
Talk is used to lower friction, not to increase it. Like sand on a road. Talc is often used as a lubricant in places where rubber would be decomposed by oil.
(By mistake I initially wrote “Talk is used to lower friction…” which, coincidentally, also happens to be true. Sometimes it takes a lot of talking though…)
How about binder or binding agent?
What if you offer it Vicodin?
I’d second the WD-40. My thought was that it would clean off the lubricant and since WD-40 tends to be temporary (really, has anyone ever WD-40’d a squeky hinge and not had to do it again a month later) it might cease up a bit once the WD-40 dries.
“Irritant,” “abrasive” or “coyote ugly,” depending on context.
LOL Yep, that’ll solve the problem!
Seriously, use any degreaser but as Omegaman suggested Carb or Brake cleaner would be the best.
I buy this guys calendar every year. Amazing the number of people who just look, but don’t read the message.
Sure, but in the case of hinges where oil has already been applied, I think there’s a chance that talc will mop up some of the oil and reduce overall lubrication.
