If you've ever reached for your outdoor trash can on a sunny day and been met with a scorching surface, you know how unpleasant and even dangerous it can be. A metal trash can sitting directly in the sun can absorb immense heat, making it hard to handle and potentially damaging its contents. Fortunately, there are several straightforward strategies you can use to keep your bin cooler.
The most effective method is to provide shade. If possible, move your trash can to a naturally shaded area, such as under a tree, a porch overhang, or the eaves of your house. This simple relocation can dramatically reduce its direct exposure to the sun's rays. If moving the bin isn't an option, consider creating your own shade. You can install a simple shade sail or even place a large patio umbrella nearby to cast a shadow on the can during the hottest parts of the day.
Another great solution is to use a reflective cover. A light-colored or specifically reflective trash can cover does a fantastic job of bouncing sunlight away instead of absorbing it. White is the most effective color for this purpose. You can purchase a custom-fit cover or even use a light-colored tarp or an old white bedsheet secured with a bungee cord. This layer of protection acts as a barrier, significantly lowering the metal's temperature.
For a more direct approach, you can apply a cool, damp towel to the lid and sides of the can on extremely hot days. As the water evaporates, it will naturally cool the metal—a process known as evaporative cooling. Just be sure to re-wet the towel as it dries out. When you first place your trash can outside, try to position it facing north or south rather than directly east or west. This minimizes the surface area exposed to the intense morning and afternoon sun.
With these easy tips—finding shade, using a reflective cover, and smart placement—you can effectively prevent your outdoor metal trash can from becoming a solar oven. A cooler bin is safer to touch and helps control odors, making your outdoor space more pleasant overall.
