Q: Is there a quick fix for a squeaky door hinge?
A: Here’s one method that sometimes works: petroleum jelly. Start by loosening the door hinge. To do so, keep the door closed and tap an 8d nail into the hinge from below, driving the hinge pin upward. Work on one hinge at a time. When the pin is out, lightly coat it in petroleum jelly—it sticks well and won’t leak out like other lubricants. Reinsert the pin, wipe of any excess, and move on to the next problem hinge.
