Do you have an old dresser that drives you nuts everytime you go to open it? When you are in a rush and your hands are full and you try to pull it open with one hand? Old wooden drawers will start to stick over time due to humidity in the wood or the loosening of the structure after repeated humidity and dryness expands and contracts the whole. If you continue to force drawers that are sticking you can cause even more damage to the frame.
By taking a regular bar of soap and rubbing it underneath on the rail of the drawer you will restore it to easy opening and closing (hard soap works better than soft). Wherever the moving wood touches is where you want the soap. You will also find that rubbing soap in the joints of squeaky wood furniture (such as a bedframe) will eliminate creaks and squeaks there as well. MGR
