Tea: If you don't like coffee, you can use tea bags instead. Just place 2-3 tea bags inside the confined space. The tea leaves in the bags will not only absorb the trash can smell but will also release the natural aroma of tea.
There are also trash chances that are made from plastic and steel as well. When steel will be used, it will make it more robust and this it will also be easier to clean. You will be very happy to know that one such model features a lid that is fingerprint resistant that is also very much protected by the manufacturing process, making it withstand scratches and dents. They are very much hard to damage and on top of that, the volume that they feature will allow you to deposit a lot of garbage into them.
