Lemon or Lime Peels: Just put some lemon or lime peels into an uncovered container and leave them inside the confined area for a couple of days. The citrus smell will naturally replace the bad trash can smell.
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.
