Orange peels: Get an orange and poke it with a sharp object like a needle or fork to form small holes. Place each of the cloves inside these small holes until most of the orange surfaces are covered. It may look like a hedgehog with the cloves jutting out of the orange fruit. Leave it in the confined area for a couple of days. The area will smell nice with the said combinations.
Baking soda: This is also a good absorbent. Put a generous amount of baking soda in an uncovered container (the size of the container depends on the size of the confined area) and leave it for several days. Remove the baking soda and replace it with new one and leave it for a couple of days. Continue replacing the baking soda until it has cleared the trash can smell.
