Outdoor trash cans often develop a sticky, paraffinic residue due to the accumulation of grease, food waste, and other organic materials. This residue not only creates unpleasant odors but also attracts pests. Here are some effective ways to prevent and remove it:

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

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

3. Baking Soda & Vinegar: Sprinkle baking soda inside the bin to neutralize odors, then spray a vinegar-water solution to break down residue.

4. Avoid Greasy Waste: Dispose of oily or greasy items in sealed containers before placing them in the trash to reduce residue formation.

5. Sun-Drying: After cleaning, leave the bin in direct sunlight to dry completely, as UV rays help kill bacteria and prevent residue.

By following these steps, you can keep your outdoor trash cans clean and free from paraffinic residue.
