Outdoor trash cans often develop a sticky, greasy residue known as paraffinic film, which attracts pests and causes unpleasant odors. To prevent this issue, follow these practical steps:

1. Regular Cleaning: Wash trash cans monthly with hot water and dish soap or a degreaser to break down oily residues.

2. Use Liners: Heavy-duty trash bags reduce direct contact between waste and the bin, minimizing film buildup.

3. Absorbent Materials: Place baking soda or cat litter at the bottom to absorb liquids and neutralize odors.

4. Avoid Greasy Waste: Dispose of cooking oils and fatty foods separately to prevent residue accumulation.

5. Ventilation: Keep lids slightly ajar or drill small holes to allow airflow and reduce moisture buildup.

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