What to Do If You Have a Squeaky Door
If you have a door that is a little squeaky when you open it, the fix is simple. All you need is a silicone-based lubricant. While you can use WD-40 or other oil-based lubricants, they tend to dry out faster and attract dust.
Start by opening your door all the way and lubricating the hinges, focusing on all the hinge points. Once you’ve applied some lubricant, open and close the door a few times to work it in. You should have a nice, quiet door again.
Summary:
To fix a squeaky door, use a silicone-based lubricant on the hinges. Apply it generously to all hinge points, then open and close the door to distribute the lubricant. This will help eliminate the squeak and restore quiet operation.
