That's a great question! Dealing with a smelly outdoor trash can is a common headache, but thankfully there are some really effective ways to tackle it. The best approach combines a thorough cleaning with ongoing odor prevention.
First, give your can a deep clean. Empty it completely and take it to a well-ventilated area, like your driveway. Hose it down to remove loose debris. Then, create a powerful cleaning solution. A classic and highly effective option is a mixture of white vinegar and baking soda. Sprinkle a generous amount of baking soda on the bottom and sides, then spray or pour white vinegar over it. Let the fizzing action work for 10-15 minutes to break down grime and neutralize odors. For tougher smells, you can use a diluted bleach solution (one part bleach to ten parts water) or a dedicated all-purpose cleaner. Scrub the interior thoroughly with a long-handled brush, paying special attention to the bottom and corners. Rinse it completely and let it air dry in the sun, as sunlight is a natural disinfectant.
For ongoing odor control, prevention is key. Always use sturdy trash bags to prevent leaks. After each emptying, sprinkle a layer of baking soda, cat litter, or even coffee grounds at the bottom of the can before inserting a new bag. These substances are excellent at absorbing moisture and neutralizing smells. For a fresh scent, you can add a few drops of an essential oil like tea tree, lemon, or eucalyptus to your baking soda base.
The most important habit is to rinse the can periodically, ideally once a month, to prevent odor-causing bacteria from building up. With this simple routine, your outdoor trash can will stay fresh and odor-free.
