Pandan Leaf: It is easy to get pandan leaf in tropical countries as it is widely used in Southeast Asian cooking to add aroma to dishes. Its pleasant aroma also acts as natural air freshener. Just take a few strips of the pandan leaves and tie them into knots. Place the leaves inside the confined space and leave them until the leaves are withered or dried up. Replace the leaves regularly until the trash can smell goes away.
It is not an easy task however, to remove trash can smells, especially within a confined area, for instance in the refrigerator, in the trunk at the back of your car, in the wardrobe or in a poorly ventilated tiny room nearest the can.
