Deodorize Your Fridge/Freezer
Something in the fridge gone bad? Once you throw out the offending item, fill a bowl with dried coffee grounds and place in your refrigerator. In a few days, the spoiled smell will be gone, replaced with a pleasant coffee aroma. This also works in your freezer when you need to remove those food odors that are making your ice cubes taste funny.
And Your Car!
Coffee is so fragrant that you can use old coffee grounds wherever you have an odor problem. Try it out in the car, especially if you have kids, pets, or are the designated carpool driver. First, dry out the grounds on a baking sheet. Then fill an old dress sock or nylon stocking with the grounds and tie it off the end. Instant air freshener!
Clean Pots and Pans
While we wouldn't recommend dumping old coffee grounds down your drain, you can use them to clean pots and pans. Just sprinkle some grounds on the caked-on, baked-on mess and scrub thoroughly. It works great on cast iron, too.
Clean Your Hands
The next time you're cutting onions, garlic, or cooking fish, rub some coffee grounds between your hands. They're help to eliminate the strong smell. Coffee also makes for a great exfoliant—just follow up with soap to kill germs.
