Those fizzing tablets used to get dentures sparkling clean have myriad uses around the house. If you have reusable plastic storage containers that have been stained or have an odor from, say, leftover eggplant Parmesan, fill the container with warm water and two tablets. Wait an hour, and rinse to reveal a like-new container. This also works wonders on coffee-stained mugs and cups. And if you love your slow cooker, use tablets to get the inside sparkling clean.
