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

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!

You can use it, may have to spray it once or twice a year but Silicone Lubes will not attract dirt/dust(a problem when using grease/oil) and will keep things quiet(more than a few days). People are stating somethings that are all in the past when WD40 only had Penetrating Spray.
