When it comes to the automatic ones, they will feature a sensor and when you will have a trash bag that will be ten inches above it and at a one hundred and thirty degree angle from it, the trash can will automatically open. If you are using it in normal parameters, then you will be able to use this amazing feature for 6 months until the batteries will run dry. This collapsible trash can works with 4 D-size batteries.
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.
