Many of the newer designed trash containers have hooks on their upper rims for grocery bag handles as the number of trash bags used in a week is approximately the same number of bags brought home from the grocery stores. Customers find that the 13-gallon bags at stores are cheaper than the odd sized ones and are more apt to be on sale. With the average trash emptied every night, the trash odor does not have time to accumulate in the plastic trash container.
Charcoal: Charcoal is on the top of the list of smell deodorizers as it is one of the best absorbent agents that can soak up the bad odor. Charcoal is also widely used as water filters and in most odor-removing commercial products. You can put a medium-sized chunk of charcoal inside your smelly patio for instance, and leave it there for a couple of days. You will notice that it can effectively remove the trash can smell.
