URBAN TRASH CANS

Honestly, the best way is to treat it like a two-part job: remove the dirt that holds odor, then kill and neutralize what's left. Start by putting on gloves, eye protection, and a mask, and move the bin to a safe wash area—ideally a concrete pad with drainage to a sanitary sewer, not a storm drain. Empty all loose trash, scrape out stuck food or gum, and rinse the worst of it away. For stains and grease, spray a heavy-duty alkaline degreaser or enzyme cleaner inside the bin, on the lid, wheels, and bottom, and let it sit for 5–10 minutes. Scrub with a stiff brush, paying extra attention to corners, seams, and the underside of the lid, because that's where odor hides. Then pressure-wash or hose it out, keeping the nozzle far enough away that you don't crack the plastic. Rinse thoroughly. For odor, use a disinfectant or enzyme odor neutralizer—don't just cover it with perfume. Avoid mixing bleach with acidic or ammonia-containing cleaners, and be careful with urine residue. Let the bin dry completely in the sun with the lid open, or wipe it dry, because moisture brings the smell back fast. If you can, sprinkle baking soda or use an enzyme spray after drying. To keep it fresher, use liners, wash weekly in warm weather, keep the lid closed but not sealed when wet, and repair cracks where liquid collects. For really bad urban bins, a scheduled professional steam cleaning every few months is worth it.
