Listen and determine where the creak is coming from. Check all of the rocking chair’s joints to see if there are any bolts, screws or other parts that may have come loose and are causing the creaking.
Adjust all loose items as necessary using a screwdriver, wrench or mallet. Re-glue any wood joints with carpenter’s glue if necessary to stop the creaking.
Wash down a wood rocking chair with an oil soap or rub down joints with talcum powder. Spray the joints of a metal rocking chair with a metal lubricant or cooking spray. Beeswax can also be rubbed over the joints of either a metal or wood rocking chair.
Use a humidifier in your home and place it near the rocking chair. Sometime wood can dry out over time and create a creaking sound when it gets too dry.
