Reusing glass jars with lids is an eco-friendly and economical way to store food, spices and other perishables in the refrigerator. But sometimes glass jars can have a slight odor. Use newspaper to remove the smell. It's simple -- since newspaper is designed to absorb ink, it absorbs others things, too, like odors. Just crumple a page you're done reading and place it inside the jar. Let it sit for several days. Remove the paper, rinse and you've got a completely odorless jar.
