Dealing with a smelly outdoor trash can is no fun, but a good clean makes a huge difference. Here's a simple, effective method you can do at home. First, take the can to a sunny, open area like your driveway. Put on some rubber gloves for protection. Empty out any loose debris and give it a strong rinse with your garden hose to remove surface grime.
Next, it's time for a deep clean. Mix a gallon of warm water with a cup of white vinegar or a generous squeeze of dish soap. For tough odors, baking soda is your best friend—sprinkle a good amount inside. Scrub every surface, especially the bottom and sides, using a long-handled brush with stiff bristles. Don't forget the lid!
After scrubbing, rinse everything thoroughly until the water runs clear. Now, let's disinfect. You can use a commercial disinfectant spray or make a bleach solution (one part bleach to nine parts water). Spray or wipe the entire interior and let it sit for about 10 minutes before a final rinse.
The last step is crucial: let it dry completely in the sun before putting a new bag in. Sunlight is a natural odor fighter. For maintenance, sprinkle a little baking soda in the bottom of the can each time you change the bag. Doing this deep clean every few months will keep those nasty smells away for good.
