Deodorizer
Dry them out on a cookie sheet and then put them in a bowl in your refrigerator or freezer, or rub them on your hands to get rid of food prep smells.
Plant food
Plants such as rosebushes, azaleas, rhododendrons, evergreen and camellias that prefer acidic soils will appreciate the leftovers from your morning cup. Also, grounds can add nutrients to your compost bin.
Insect repellant
Sprinkle old grounds around places you don’t want ants, or on the ant piles themselves. Used grounds are also said to repel snails and slugs.
Dye
By steeping grounds in hot water, you can make brown dye for fabric, paper and even Easter eggs.
Furniture scratch cover-up
Steep grounds and apply a bit of the liquid to furniture scratches with a Q-tip.
Cleaning product
As they’re slightly abrasive, grounds can be used as a scouring agent for greasy and grimy stain-resistant objects.
Kitty repellent
To keep kitty from using the garden as her personal powder room, sprinkle grounds mixed with orange peels around your plants.
Flea dip
Follow up Fido’s shampoo with a coffee ground rub down, working them down to his skin. Not only are the fleas suppose to disappear, but puppy’s hair will feel soft too.
Dust inhibitor
Before you clean out the fireplace, toss wet coffee grounds over the ashes to keep the ash dust under control.
