Plastic trash cans are easy to clean and keep odor free, with grocery bags helping to lower trash liner expenses, all this adds up to make this type of trash container one of the more popular ones. By emptying the bag daily, there is no chance of an odor building up. A useful tip is to make sure the trash liner fits the can and is not so small that the bag slides down, allowing food and odor to accumulate throughout the day. Also, hose the trash can down outside on a daily basis if it needs it, while using a sponge with dishwater liquid to clean the stains that remain.
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.
