That's a common and frustrating issue! Those dark, greasy stains under the bin are not only an eyesore but can also attract pests. Don't worry, preventing them is easier than you might think. Here are some practical, real-world solutions.
First, create a physical barrier. Placing a durable, absorbent mat underneath your trash can is the simplest defense. Look for a heavy-duty plastic or rubber mat designed for outdoor use. For a more natural look, a bed of large, smooth pebbles or gravel works wonders—it lifts the can slightly and allows for drainage. You can also use concrete pavers or a small plastic pallet to keep the base elevated and dry.
Next, tackle the source: leaks. Always use a sturdy, leak-proof liner bag, and consider doubling up if you dispose of wet waste or liquids. Give your kitchen trash can a quick rinse with a mild disinfectant every time you take out the full bag to prevent grime buildup that eventually seeps out. For your outdoor bin, a deep clean with soap and water every few months makes a huge difference.
Be proactive with placement. If possible, move your bin a few inches every week to prevent moisture from being constantly trapped in one spot. For persistent problems, consider upgrading to a trash can with a sealed, leak-proof base or a wheeled design that keeps the bottom off the ground.
Finally, for existing stains, a paste of baking soda and water or a dedicated concrete cleaner can often lift the mark. Scrub, let it sit, and rinse thoroughly. With these consistent habits, you can easily keep your pavement clean and stain-free.
