I lubricated the hinges of a noisy door

you didn't mention which lubricant, hope it wasn't WD40, as people tend to grab it for these things, but the solution usually ends being temporary
- To back you up, WD40 stands for Water Displacer, 40th try.
  While it does kind of lubricate, that isn't what it's meant for, and the leftover ingredients will not keep it lubricated long and possibly cause more damage in the long run.
  WD40 to help restore motion to the joint, then clean, then oil. Or just oil if it moves easily.
  
  Though PB blaster always seems to work better to me. My applications are usually related to loosening stuck/rusted bolts and such.
- I used this, no WD40 😊
  
  Did that run in okay? Lithium grease is usually quite chunky. 3 in 1 do a standard oil which I use for doors. Lithium grease is something I normally use on the car.
- What else are you supposed to use?
  
  Liquid Wrench is pretty good.
  
  A lubricating oil. I like ProTecta.
  
  Molybdenum disulfide is really good
  
  How about anything with the word “lubricant” in it. The WD stands for Water Displacement, so it was designed to displace water, which it does. It also kinda lubricates, but it’s far from being a good lubricant.
  
  If you don't feel like going to the store, petroleum jelly is a half decent solution for squeaky door hinges. Lasts quite a few years too.
  
  You can just use olive oil; works great.
- Exactly. Just yesterday I had to recommend someone use an actual lubricant for a lock...
  
  Isn't graphite powder normally the best solution for locks?
- I use wd40 and it's fine! The lithium wd40 i mean.
- What you're saying is true in general but it works pretty well and for a fairly long time in door hinges.
- All solutions are temporary bro.

It's always a joy to do that, especially if the door is frequently used. All of a sudden your surroundings get a lot nicer.

I did this with my garage door the other day. The thing squealed like crazy since we bought the house and I didn't really know how to fix it. Got some White Lithium Grease and just sprayed it into all of the hinges, greased the top rail and tightened the chain. I just love that I don't have to cringe every time I'm about to press the button to open the door.
