It's a common and frustrating problem: you lift your outdoor trash can, only to find a pool of murky water at the bottom and the beginnings of rot. This not only shortens the life of your bin but also creates unpleasant odors and attracts pests. The good news is that preventing this is straightforward. The core principle is simple: manage moisture. You need to either let the water out, keep the water from sitting against the bottom, or create a barrier. Here are the most effective strategies.
First and foremost, ensure proper drainage. This is the single most important step. If water can't pool, it can't cause rot. Carefully drill a series of small holes (about 1/4 inch or 6mm) in the lowest points of the bin's bottom. Don't make them too large, or small debris will clog them. A few well-placed holes will allow any rainwater or liquid from bags to drain out naturally.
If you're hesitant to drill into your bin, elevate it. Place your trash can on a stable, raised platform. This can be a simple DIY project using bricks, concrete blocks, or a wooden pallet. By lifting the bin just a few inches off the ground, you promote air circulation underneath, which helps the bottom dry quickly and prevents constant contact with damp surfaces.
Another excellent line of defense is using a protective liner or mat. Place a heavy-duty rubber mat, a piece of leftover vinyl flooring, or even a thick layer of gravel inside the bottom of the can before you put your trash bag in. This creates a physical barrier that separates your trash bag from any residual moisture that might accumulate.
Regular cleaning is also crucial for longevity. Periodically, give your trash can a thorough scrub. Empty it completely, then use a long-handled brush, a mixture of dish soap or vinegar, and a hose to rinse it out. Let it dry completely in the sun before putting a new bag in. This prevents the buildup of grime and acidic substances that can degrade the plastic over time.
Finally, for an extra layer of protection, consider a waterproofing treatment. You can spray or wipe a silicone-based waterproofing spray on the clean, dry bottom of the bin, both inside and out. This helps bead up water and adds a protective coating to the plastic.
By combining these methods—especially drilling drainage holes and elevating the bin—you will effectively combat moisture and significantly extend the life of your outdoor trash can, saving you money and hassle in the long run.
