That's a common and frustrating problem! Water pooling at the bottom of a trash can is a recipe for rot, rust, and awful smells. Here’s a natural, practical guide to tackle it, just like I would for my own bin.
First, prevention is key. Always use a sturdy, fitting plastic bag liner, and make sure it covers the entire bottom and sides. Double-bagging for wet waste is a smart move. When you take out the full bag, take an extra 30 seconds to wipe the inside bottom dry with an old towel or paper towels. This simple habit makes a huge difference.
If water still finds a way in, you need to address drainage. For plastic cans, you can carefully drill a few small holes (1/4 inch) in the very bottom of the side walls, not the flat base. This lets water seep out without creating a large weak spot. Place the can on a couple of bricks or a small, elevated stand to allow air circulation underneath and let those drainage holes work.
For metal cans, rust is the enemy. After drying it thoroughly, apply a rust-inhibitive spray paint or a clear waterproof sealant to the interior bottom. A rubberized undercoating spray (used for cars) is also an excellent, durable barrier.
Your location strategy matters. If possible, keep your trash can in a shaded, covered area like under an eave or a simple DIY canopy. This minimizes direct rain and sun exposure, which accelerates material breakdown.
Finally, give it a deep clean monthly. Empty the can, scrub it with a mild detergent and water, and let it dry completely in the sun before putting in a new liner. The sun is a great natural disinfectant and dryer.
Staying ahead of the moisture is the real secret. A dry can is a long-lasting, odor-free can.
