That's an excellent question, and it's something many homeowners worry about. To put it simply, yes, the bottom rusting out is one of the most common failure points for a metal outdoor trash can. It's not a matter of *if* but *when* for most standard cans. The bottom is the most vulnerable area because it's in constant contact with moisture. Rainwater, sprinklers, and even the dampness from the trash itself collect at the bottom and never fully evaporate. This creates a perpetually damp environment that accelerates corrosion. Furthermore, any scratches or chips in the protective paint or galvanized coating from moving the can or tossing in heavy bags expose the raw steel underneath, inviting rust to form.
So, what can you do about it? Prevention is key. First, always look for trash cans made of galvanized steel, which has a zinc coating that provides superior rust resistance. Ensure the can has adequate drainage holes in the bottom to allow water to escape. Placing the can on a simple wooden pallet or bricks can also dramatically improve airflow and prevent puddling. For a can you already own, you can fight back. Clean it regularly to remove corrosive debris. If you see minor rust, sand it away and apply a rust-inhibiting spray paint designed for metal. While no metal can is entirely immune forever, choosing a well-made, rust-resistant model and performing these simple maintenance steps will add years to your trash can's life.
