Outdoor trash cans often develop a sticky, wax-like residue known as candelillic residue, which can attract pests and create unpleasant odors. To prevent this buildup, follow these practical steps:

1. Regular Cleaning: Wash your trash cans monthly with hot water and a degreasing detergent. Scrub the interior thoroughly to remove any lingering residue.

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

3. Avoid Oily Waste: Dispose of greasy or oily materials in sealed containers before placing them in the bin to reduce residue formation.

4. Apply a Protective Coating: Spray the interior with a silicone-based lubricant or non-stick cooking spray to create a barrier against sticky residues.

5. Keep Lids Closed: Ensure lids are tightly sealed to prevent moisture buildup, which can accelerate residue formation.

By adopting these habits, you can maintain cleaner, odor-free outdoor trash cans and extend their lifespan.
