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

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

2. Use Liners: Always line your trash cans with durable bags to minimize direct contact between waste and the bin’s surface.

3. Baking Soda Sprinkle: After cleaning, sprinkle baking soda at the bottom to absorb odors and reduce moisture, a key factor in film formation.

4. Avoid Oily Waste: Dispose of greasy or oily materials separately, as they contribute heavily to carnauba film.

5. Sun-Dry After Washing: Allow the bin to dry completely in the sun before reuse, as moisture accelerates residue buildup.

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