Stop the squeak with one the most versatile products in the pantry: olive oil.
Just a tiny bit of this liquid gold works wonders on sticky hinges.The oil can be applied with a small brush or wiped on with a cloth. Only a small amount is needed to do the trick, so dab away any excess and be sure the surface is free of dust and grim before you start—you don’t want the stuff going rancid! If you are out of olive oil, vegetable oils also work as a natural alternative to WD-40 and the like.

Ewwww. I HATE when people paint over hinges. But I can attest to the effectiveness of olive and/or vegetable oil for de-squeaking door hinges. AND it smells much nicer than WD-40.
Food safe mineral oil found at the pharmacy is probably the better alternative to WD-40 for lubricating door hinges than vegetable oils which do oxidize and become rancid regardless of how clean the hinge is. Using small amounts will probably make any foul odors negligible; however, the issue of the oxidizing oil becoming tacky/gummy is probably more problematic.
Since only small amounts are being used, buildup will be slow, so it will probably be a long while before the hinge becomes sticky or gummed up.
Another alternative, though not so green is using Pledge, which is pretty good at dissolving grime while leaving a basically lubricated surface.
I mixed a few drops of tea tree oil with the olive oil and applied sparingly. Seems to have done the trick perfectly. Hoping the tea tree oil will keep the olive oil from getting rancid or sticky.
Sadly, my apt. door hinges look just like the ones in the photo.
Forgot to mention that the ratio of tea tree oil to olive oil was actually about 50-50.
