Water Rings on Wood... Set a cold drink on your wood furniture without using a coaster and you’ll leave a round reminder not to do it again. To remove it, dip a white cloth in a mixture of equal parts vinegar and vegetable oil, and rub out the stain, wiping with the grain. Then clean the area with a dry cloth to make the wood shine. You can also remove water rings from leather furniture by dabbing them with vinegar on a cloth.
