How to Remove Unpleasant Smell from Jars

I have been reusing jars around the house, but just hate those distinct odors that get left behind... pickles, herbs, coffee, you name it. The smell gets attached to whatever item you fill it with. So what i do is fill the jar up with crumpled newspaper and let stand overnight, or even longer. The newspaper will absorb any distinct smell from the jars. I've tried it and it worked wonders! It can also be used to remove odors from cars. Just leave a couple of newspapers all year round, replacing once in a while. Or only when there's a need for it.
