#2. Freshen Rooms and Cupboards
The next time you need to freshen up a room or a musty closet try boiling a few orange peels and allowing the smell to fill the area. You can even add a few sprigs of mint and / or some cinnamon sticks for an even fresher smell. For areas such as your living room, put some orange peels into a small glass or other container and leave it on your table.
