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.
These outdoor trash receptacles will often have some kind of cover that will both keep any waste inside the bin while also making the can easily accessible. Some of these covers may have flap doors in the front while others may simply have a lid with open sides.
