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.
The plastic trash can has been around for a long time, but not the automatic types you can get today. There are many durable plastic models on the market, fitting in any room in the home or office.
