Outdoor trash cans often develop a musty smell due to moisture, bacteria, and decaying waste. To prevent this issue, follow these practical steps:

1. Regular Cleaning: Wash the trash can weekly with a mixture of water and vinegar or mild detergent. Scrub the interior and exterior to remove residue and bacteria.

2. Proper Drying: After cleaning, leave the bin upside down to air-dry completely before relining it. Moisture trapped inside can cause mold and odors.

3. Use Baking Soda: Sprinkle baking soda at the bottom of the bin to absorb odors naturally. Replace it every few days for continuous freshness.

4. Liner Bags: Always use sturdy trash bags to prevent leaks and reduce direct contact between waste and the bin.

5. Ventilation: Keep the lid slightly ajar or drill small holes at the top to allow airflow, reducing moisture buildup.

6. Essential Oils: Add a few drops of tea tree or lavender oil to cotton balls and place them inside the bin for a pleasant scent.

By maintaining these habits, you can keep your outdoor trash cans smelling fresh and free from musty odors.
