That's a great question! Yes, outdoor trash cans definitely benefit from some regular, simple maintenance. It's not complicated, but doing a few things routinely can make a big difference in controlling odors, preventing pests, and extending the life of the cans themselves.
First and foremost, regular cleaning is key. I try to give my cans a good rinse with a garden hose each time they're emptied by the collection service. For a deeper clean, about once a month or if there's a spill, I use a long-handled brush with a mixture of warm water and dish soap or a bit of baking soda. A mild bleach solution (one part bleach to nine parts water) works well for disinfecting and killing odors, but I always rinse thoroughly afterward. Just remember to wear gloves!
To manage smells between cleanings, sprinkling a handful of baking soda or cat litter in the bottom of the can absorbs liquids and neutralizes odors. It's also crucial to use sturdy trash bags and tie them securely to contain leaks. Placing the cans in a shaded spot if possible helps slow down the decomposition of waste and reduces smells.
Finally, a quick visual check for cracks or damage, especially around the wheels and lid hinges, helps catch small problems before they get worse. A well-maintained can is less attractive to raccoons, insects, and other critters. It really doesn't take much time, and it keeps the area around your home much more pleasant.
