It's a common and frustrating problem: you go to move your outdoor trash can and discover the bottom is soft, weak, or has completely rotted out. This is usually caused by moisture being trapped underneath and inside the can, leading to rust on metal cans and the breakdown of plastic polymers. Fortunately, preventing this is straightforward with a few simple habits.
The most effective strategy is to keep the bottom of the can dry and elevated. Here’s how you can do it:
1. Elevate Your Can: Never let your trash can sit directly on a wet surface like concrete or grass. Place it on a simple platform. You can use two bricks, concrete pavers, or even a small wooden pallet. This creates an air gap underneath, allowing moisture to evaporate and preventing constant contact with dampness.
2. Use a Trash Can Liner: This is a non-negotiable step. Always use sturdy trash bags. A liner acts as a primary barrier, containing leaks and preventing liquid waste from ever touching the bottom of the can. This protects both plastic and metal cans from corrosive liquids.
3. Drill Drainage Holes (For Plastic Cans): If your plastic can tends to collect rainwater or liquid spillage, carefully drill a few small holes in the bottom. Do this only on the low points of the molded base, not on the flat, weight-bearing surface. This allows any accumulated water to drain out, keeping the interior dry.
4. Clean and Dry Regularly: Periodically, give your trash can a thorough cleaning. Hose it out, scrub with a mild detergent or a vinegar solution to neutralize odors and bacteria, and then—this is the crucial part—tip it over to let it air dry completely before putting a new bag in.
5. Apply a Protective Coating: For an extra layer of defense, especially on a metal can, you can apply a waterproof sealant or a rust-inhibiting paint to the bottom, both inside and out. For plastic cans, ensure any coating you use is compatible with plastic polymers.
By following these simple steps—elevating the can, using a liner, ensuring proper drainage, and maintaining cleanliness—you will significantly extend the life of your outdoor trash can and avoid the unpleasant surprise of a rotted-out bottom.
