That's a great question! A smelly metal trash can is a common but fixable problem. Metal cans, while durable, can really hold onto odors if not cleaned properly. The best approach combines a deep clean with natural deodorizers. Here’s a simple, effective method you can try.
First, empty the can completely. If possible, take it to a grassy area or a spot where you can use a hose. Rinse it out thoroughly with hot water to remove loose debris.
Next, create a powerful cleaning paste. Sprinkle a generous amount of baking soda (about half a cup) all over the interior. Then, slowly pour white vinegar over the baking soda. It will fizz—this reaction helps break down grime and neutralize odors. Let this mixture sit for 15-30 minutes.
After it sits, use a long-handled brush with stiff bristles and some dish soap to scrub every surface, especially the bottom and sides. The baking soda acts as a gentle abrasive. Rinse everything away completely with your hose or under a strong stream of water.
This is the crucial step for metal: disinfect and dry thoroughly. To kill odor-causing bacteria, spray the inside with a disinfectant spray or a solution of one part water to one part white vinegar. Finally, let the can dry completely in direct sunlight before putting a new bag in. Sunlight is a fantastic natural deodorizer and disinfectant.
For ongoing maintenance, keep a thin layer of baking soda at the bottom of the can under the bag. Also, rinsing the can with a hose after each time you take out a full bag of trash makes a huge difference in preventing smells from building up. With this routine, your metal can should stay fresh much longer.
