This should be a relatively easy question. My doors were squeaking upon open and close. No big deal really but I took a door off and noticed some minor surface rusting at the contact points so I used some W-D and a drill with a wire brush to clean of the rust on the hinges and pins. My question is. Is there a specific or preferred type of lubrication at the pins and hinges? I.E. - Teflon powder, Graphite powder, High temp grease (I am doubtful of this but inexperienced) or any others. Any help is appreciated. I would like to extend a preemptive thank you for advice.
