Spring Fever: The best way to get rid of the trash can smell? Get rid of it from the source. Be more prudent with your waste materials. Put things away as soon as you're done using them. Throw things away as soon you know you won't use them. Everyday maintenance is the key to a breathable, livable home.
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.
