Outdoor trash cans often develop a greasy lanolin film over time, leading to unpleasant odors and bacterial growth. To prevent this, follow these practical steps:

1. Regular Cleaning: Wash the trash can monthly with hot water and a degreasing detergent. Scrub the interior thoroughly to remove residue.

2. Use Liners: Always line the bin with sturdy garbage bags to minimize direct contact with waste and liquids.

3. Baking Soda Sprinkle: After cleaning, sprinkle baking soda at the bottom to neutralize odors and absorb moisture.

4. Vinegar Rinse: Occasionally rinse the bin with white vinegar to break down grease and disinfect surfaces.

5. Sun-Drying: Allow the trash can to dry completely in sunlight after washing to prevent moisture buildup.

For long-term prevention, avoid disposing of oily or fatty waste directly into the bin. Instead, seal such items in containers before tossing. Implementing these habits will keep your outdoor trash cans clean and free from lanolin film.
