Just because you're an early riser doesn't mean a squeaky door should wake up the rest of your family. Eliminate this annoying sound by performing simple maintenance on your door hinges.
You'll need a hammer and nailset (or thick nail), a screwdriver, a cleaning rag and silicone lubricant to do this job. Basically, you'll need to find the squeaky hinge, clean it, and then apply some of the lubricant before putting it back in. If you can't tell which hinge is the problem, then you'll need to clean and lubricate all two or three of your hinges.
For safety, it's best to remove just one hinge pin at a time starting from the bottom. Check out the link below for the full instructions.
