Baking soda: This is also a good absorbent. Put a generous amount of baking soda in an uncovered container (the size of the container depends on the size of the confined area) and leave it for several days. Remove the baking soda and replace it with new one and leave it for a couple of days. Continue replacing the baking soda until it has cleared the trash can smell.
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.
