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.
Vanilla Essence: Pour several drops of vanilla essence on a couple of cotton wools. Toss the cotton wools inside the confined spaces nearest your trash can. Leave them for several days and you will notice that the area smells nice, or at least smells nicer.
