When you hear a creaky door, it usually means grabbing a petroleum-based lubricant to spray on the hinges to stop the noise. But you don't have to use a nonrenewable chemical product to have hinges move with ease. Try food-grade mineral oil (from the pharmacy) or a few drops of tea tree oil instead. These oils are made from renewable resources and will have a lasting effect to keep joints, hinges and anything else in your home moving effortlessly. Just avoid vegetable and olive oils: While they do the trick, the oil will go rancid and create an unpleasant smell.
