I have squeaking front and garage entrance door hinges in my house I
need to spray with lubrication during the winter because it gets so
loud. I used WD-40 a couple of times, but the irritating noise would
come back only after a few days.

Someone told me to give silicone spray a try, so I might do that, but
thought I'd pose a question in here to learn when using one over the
other is better.

Is metal on metal contact for WD-40 and the silicone spray for
everything else? Please clarify. Thanks!

WD-40 will evaporate after a while. Better bet for longterm is
something like motorcycle or bicycle chainlube, which is like WD40 with
molybdenum in it, or some of the lock lube liquids, which are like WD40
with graphite. Frankly, for something as delicate and refined as a door
hinge, you can use crappy old 3-in-1 or probably Crisco.

The best solution I ever found was a lubricant that the local garage door
installer sold me. Depends if your climate is an issue but where I am, this
stuff stayed pliable to temps 20 degrees below zero. Sorry don't remember
the name, but it was sold in a small squeeze tube, small application in each
hinge did the trick for years.
