CONTAINERS ...Close the container and shake it so that the insides are coated. Leave it overnight. Next morning, rinse and let air-dry. The wet way (for an l~don't-think-the-smell-will-ever-come-out container) is to fill the container with hot water, equal amounts of baking soda and white vinegar (one or more tablespoons, depending on the size of the container) and a few drops of liquid dish detergent.
