Outdoor trash cans can quickly become a source of unpleasant odors, especially in warm weather. Fortunately, there are several effective methods to keep them smelling fresh. First, line your trash can with a sturdy bag to prevent leaks and residue buildup. Regularly washing the bin with a mixture of vinegar and water can neutralize odors. Sprinkling baking soda at the bottom of the can before adding a new bag also helps absorb smells. For long-term odor control, consider using trash can deodorizers or placing activated charcoal inside. Finally, ensure proper waste segregation to reduce organic waste, which decomposes and causes bad smells. By following these steps, you can maintain odor-free outdoor trash cans effortlessly.
