The plastic trash can that is made today is perfect for bathroom with touchless faucets and automatic soap dispensers. This is the cheapest and easiest trash can to use for cleanliness. Plastic that is placed over stainless steel makes it even more robust while still being easy to clean.
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.
