Just what the doctor ordered : Fixing a Squeaky Door with WD-40

The bedroom door produced a loud, crackling noise each time it was opened or closed. This noise frequently woke up the children sleeping inside, causing disruptions during the night and during nap times. Using WD-40 on the door hinges effectively resolved the noise issue, leading to a quieter environment and undisturbed sleep for the children. This simple repair task improved the functionality of the door and the overall quality of life in the household.
