Outdoor trash cans often develop a sticky, waxy residue known as carnaubic film, which can attract pests and emit unpleasant odors. To prevent this issue, follow these practical steps:

1. Regular Cleaning: Wash your trash cans monthly with a mixture of hot water, dish soap, and vinegar. Scrub thoroughly to remove any residue.

2. Use Liners: Always line your bins with sturdy garbage bags to minimize direct contact with waste.

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

4. Avoid Greasy Waste: Dispose of oily or greasy items in sealed containers before placing them in the bin.

5. Sunlight Exposure: Occasionally leave the bin in direct sunlight to dry and disinfect naturally.

By adopting these habits, you can keep your outdoor trash cans free from carnaubic film and maintain a cleaner, odor-free environment.
