My wife and I recently moved into a new townhouse. Almost every door made a loud bang and bang when opened, much louder than a creak. The builder used graphite to solve this problem, but it didn't last long. I've tried cleaning the hinges and lubricating the hinges with mineral oil recommended by a friend; it didn't work at all. I found Upkeep Door Hinge Oil at Revain and bought it immediately. The thing works wonders. This is a high quality light machine oil in a large bottle with an applicator. I oiled ten doors in our house and they are now completely silent and open easily. I don't know how long the oil will last, but this little bottle has enough to keep my hinges lubricated and quiet for a long time. I recommend Upkeep Oil door hinge oil. It's perfect, just as advertised.
