Get those white marks—caused by hot cups or sweating glasses—off your coffee table or other wooden furniture by making a paste of 1 tablespoon baking soda and 1 teaspoon water. Gently rub the spot in a circular motion until it disappears. Remember not to use too much water to remove water stains from wood
Place a clean cloth over the heat spot. An iron set to medium heat and iron over the cloth. Pulls the moisture into the cloth.
Try rubbing a little mayonnaise on them.
This method has worked very well for me and my dining room table Sallie!
