Outdoor trash cans often develop a powdery coating due to moisture, mold, or residue buildup. To prevent this issue, follow these practical steps:

1. Regular Cleaning: Wash your trash cans monthly with a mixture of warm water and dish soap or vinegar. Scrub the interior and exterior to remove grime and prevent mold growth.

2. Dry Thoroughly: After cleaning, let the bin air-dry completely before placing a new bag. Moisture trapped inside encourages powdery residue.

3. Use Liners: Always use sturdy trash bags to minimize direct contact between waste and the bin. This reduces the chance of residue sticking to the surface.

4. Baking Soda Sprinkle: Lightly sprinkle baking soda at the bottom of the bin to absorb odors and moisture, which can contribute to powdery buildup.

5. Avoid Overfilling: Overfilled bins are harder to clean and more likely to trap moisture. Dispose of waste regularly to maintain cleanliness.

6. Sunlight Exposure: Place your trash can in a sunny spot if possible. UV rays help kill mold and bacteria, reducing the risk of coating formation.

By adopting these habits, you can keep your outdoor trash cans fresh, clean, and free from unsightly powdery coatings.
