Outdoor trash cans often develop a sticky, unpleasant kerogenous film due to residue buildup, moisture, and bacterial growth. To prevent this issue, follow these practical steps:

1. Regular Cleaning: Wash your trash cans monthly with hot water and dish soap. For stubborn film, use a mixture of vinegar and baking soda to break down grime.

2. Proper Drying: After cleaning, let the bin dry completely before relining it. Moisture accelerates film formation.

3. Use Liners: Always use durable trash bags to minimize direct contact between waste and the bin’s interior.

4. Sprinkle Absorbents: Place baking soda or cat litter at the bottom of the bin to absorb liquids and reduce odors.

5. Avoid Overfilling: Overfilled bins leak and create more residue. Dispose of waste frequently to prevent buildup.

6. Disinfect Occasionally: Spray the interior with a bleach solution (1:10 ratio) to kill bacteria and mold.

By adopting these habits, you can keep your outdoor trash cans clean, odor-free, and free from kerogenous film.
