10 clever uses for coffee grounds
Neutralize food odors
Thanks to all that nitrogen, coffee grounds absorb and banish funky food smells. Use them like you would baking soda in your fridge—just fill a small, open container with grounds and stick it in on a shelf. After a few weeks, replace the old grounds with “new” ones and transfer the outgoing grounds to your garden or compost heap. Here’s another odor-taming trick: Keep a cup of grounds near your kitchen sink and rub them all over your hands after you chop garlic, onions or other pungent foods. Rinse and walk away clean—no lingering odor.
