"Eliminate Tupperware Odors with a Clever Coffee Ground Trick"
If you have smelly Tupperware, you can eliminate the odors by placing fresh coffee grounds in the container overnight. Coffee contains nitrogen, which minimizes oxidation and helps keep food smelling fresh. For stubborn odors, mix water and baking soda to create a paste, apply it inside the containers, let them sit for a day, and rinse clean. This hack allows you to repurpose your Tupperware and avoid adding to landfill waste.
