Outdoor trash cans often develop a sticky, unpleasant residue known as kerogenous buildup due to prolonged exposure to waste and weather. 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 grime and bacteria.

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

3. Apply Baking Soda: Sprinkle baking soda at the bottom of the can to neutralize odors and absorb moisture, reducing residue formation.

4. Avoid Overfilling: Prevent spills and leaks by not overfilling the bin, which can lead to residue accumulation.

5. Choose the Right Location: Place trash cans in shaded areas to reduce heat exposure, which can accelerate residue buildup.

By implementing these strategies, you can keep your outdoor trash cans clean, odor-free, and free from stubborn kerogenous residue.
