Noticing rust at the bottom of your metal urban trash can? Don't rush to replace it just yet! Many cases of bottom rust can be effectively repaired, saving you money and keeping a usable item out of the landfill.
First, assess the damage. Is the rust only superficial, creating surface stains, or has it eaten completely through the metal, creating holes? For superficial rust, a simple repair is very possible.
Start by emptying and thoroughly cleaning the can. Let it dry completely. Put on safety glasses and gloves, then use a wire brush or coarse-grit sandpaper to scrub away all the loose rust and flaky paint. Your goal is to get down to bare, solid metal.
Next, apply a rust converter or inhibitor. This chemical solution reacts with the rust, turning it into a stable, paintable black surface. Once that has dried, it's crucial to protect the area. Apply a metal primer designed for rust prevention, followed by a few coats of durable, rust-resistant spray paint. This creates a protective barrier against future moisture.
So, when should you replace it? If the rust has created significant holes, especially large ones or multiple small ones, the structural integrity is compromised. If the bottom feels soft or flexes easily, it's time for a new can. Continuous leaks from holes are a clear sign for replacement.
To prevent rust from coming back, always ensure your can is completely dry inside before putting in a new bag. Avoid letting wet waste sit directly on the bottom for long periods. A simple platform or bricks underneath the can can also improve airflow and prevent water from pooling.
With a little effort, you can often extend the life of your metal bin for several more years. It’s an easy, sustainable win
