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

1. Regular Cleaning: Rinse your trash cans weekly with a high-pressure hose or scrub them with a mixture of hot water and dish soap. For deeper cleaning, use a solution of white vinegar and baking soda to break down residue.

2. Use Liners: Always line your trash cans with durable bags to minimize direct contact between waste and the bin’s interior. This reduces the chances of residue adhering to the surface.

3. Avoid Oily Waste: Dispose of greasy or oily materials in sealed containers before placing them in the trash. These substances are primary contributors to ozoceritic residue.

4. Apply Protective Coatings: Spray the interior of your trash can with a silicone-based lubricant or a non-stick cooking spray. This creates a barrier that makes residue easier to wash off.

5. Sun-Dry After Cleaning: After washing, leave the trash can upside down in direct sunlight to dry completely. Sunlight helps kill bacteria and prevents moisture buildup, which can accelerate residue formation.

For existing ozoceritic residue, use a degreaser or a commercial trash can cleaner. Scrub with a stiff brush and rinse thoroughly. Consistent maintenance is key to keeping your outdoor trash cans clean and odor-free.
