Outdoor trash cans often develop a milky residue due to moisture, bacteria, and organic waste buildup. To prevent this, follow these simple yet effective tips:

1. Regular Cleaning: Wash your trash can monthly with a mixture of warm water and dish soap or vinegar. Scrub the interior thoroughly to remove residue and bacteria.

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

3. Dry Completely: After cleaning, let the trash can dry in the sun to eliminate moisture, which contributes to residue formation.

4. Baking Soda Sprinkle: Sprinkle baking soda at the bottom of the bin to absorb odors and reduce bacterial growth.

5. Avoid Overfilling: Prevent liquid waste from pooling by not overfilling the bin, and dispose of wet trash separately.

By adopting these practices, you can keep your outdoor trash cans clean, odor-free, and free from unsightly milky residue.
