Another nerd - it’s because the solvent in WD-40 cleared out the dirt that was causing the squeak. But you should hit the hinges with some lubricant if you’d like a longer-lasting squeak-free house.
This nerd is right, and ive worked as a handyman for too long before i knew this and didnt have to go back to some people for squeaking doors because i started doing wd40 first and then lube it with grease.
