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.
However, while such trash bins are not flashy or fun, they are incredibly necessary in order to maintain a clean and sanitary business place. Customers need to have access to outdoor trash receptacles, and providing such bins in strategic locations can help improve the cleanliness both inside and outside the business. It is also important to consider outdoor commercial trash cans for employee usage, in order to keep waste manageable and outside the main area of business.
