The fastest way to clean a smelly trash can is to empty it, rinse it outdoors, scrub it with hot water and dish soap, disinfect it, let it dry completely in the sun, and finish with baking soda. The whole routine takes about 20 minutes.
Key takeaways
- Odor comes from bacteria feeding on food residue and leaked liquid, so you must clean a smelly trash can itself, not just change the bag.
- The right order is soap and hot water first, disinfectant second, and complete drying third.
- Never mix bleach with vinegar or ammonia, because the combination can release dangerous fumes.
- A weekly rinse and a monthly deep clean keep the smell from coming back.
You lift the lid, a wave of stale, sour air hits you, and you realize the bag was never the real problem. The can itself is. If you have been searching for a dependable way to clean a smelly trash can, you are in the right place. This guide shows exactly how to clean a smelly trash can from top to bottom, which products are worth buying, and which habits stop the odor from returning.
Whether you own a small kitchen step can or a large rolling bin, the process is almost the same. Once you know how to clean a smelly trash can the right way, you will rarely need a full deep clean more than once a month.
Why Does a Trash Can Smell So Bad?
Trash can odor is mostly biology. Food scraps, meat juices, wet paper, and diapers break down quickly, and bacteria and mold feed on whatever residue is left behind. Heat and moisture speed everything up, which is why it is so important to clean a smelly trash can before the bacteria multiply. Liquid that leaks past the bag, often called garbage juice, pools at the bottom, soaks into the plastic, and seeps into seams, hinges, and the rim.
That is why swapping the liner rarely helps. To clean a smelly trash can properly, you have to treat the whole container, including the lid, the underside of the rim, the exterior, and any foot pedal.
| Source of Odor | Where It Hides | Best Fix |
|---|---|---|
| Leaked garbage juice | Bottom corners and seams | Hot soapy scrub plus an enzyme cleaner |
| Greasy food film | Inner walls | Dish soap and a long-handled brush |
| Mold and mildew | Lid underside and rim | White vinegar, then sun drying |
| Trapped moisture | Under the liner | Full air drying before a new bag |
| Scratched, worn plastic | Old cans | Deep soak or replacement |

How to Clean a Smelly Trash Can: Step-by-Step Method
Follow these seven steps in order. The sequence matters, because each step prepares the surface for the next one.
Step 1: Empty the Can and Move It Outside
Before you clean a smelly trash can, remove the bag, tie it, and take the can to a driveway, patio, or lawn. Working outdoors keeps the smell and the mess away from your kitchen. If you cannot go outside, use a bathtub or utility sink and open a window. Wear rubber gloves for the whole process.
Step 2: Rinse Out the Loose Debris
Spray the inside with a garden hose, or use a bucket of water if you need to clean a smelly trash can in an apartment. This first rinse removes surface grime so your cleaner can reach the stubborn residue underneath.
Step 3: Scrub With Hot Water and Dish Soap
Add a few squirts of Dawn Ultra Dishwashing Liquid and a few inches of hot water. Use a long-handled brush to scrub the bottom, corners, walls, rim, and lid. Dish soap cuts through grease, which is the sticky layer that traps odor. If you need to clean a smelly trash can that has been neglected for months, let the soapy water sit for 10 to 15 minutes before scrubbing.
Step 4: Disinfect the Surface
For a gentle option, fill the can about one quarter full with equal parts white vinegar and hot water, swish it around, and let it sit for 15 minutes. Vinegar is a simple way to remove garbage can smell from light odors and mildew.
For a heavy-duty option to disinfect a garbage can, mix about one third of a cup of household bleach into one gallon of cool water, which matches the general disinfecting dilution the CDC publishes. Swish it around and let it sit for about five minutes. Always check your bleach label, and never combine bleach with vinegar, ammonia, or any other cleaner.
Step 5: Treat Stubborn Odors With Baking Soda or Enzymes
If the smell survives the wash, sprinkle baking soda over the damp bottom and walls, scrub it into a paste, and leave it for 30 minutes. For sour smells from meat or fish, an enzyme cleaner such as Nature’s Miracle Advanced Stain & Odor Remover breaks down the organic residue that soap leaves behind. Follow the label for contact time.
Step 6: Rinse and Dry Completely in the Sun
Rinse away every trace of cleaner, then set the can and lid upside down in direct sunlight for at least an hour. Moisture is the main reason people fail to clean a smelly trash can for good, because a damp interior grows bacteria again within days. Sunlight and airflow also help discourage mildew.
Step 7: Deodorize and Re-Bag
Once the can is completely dry, sprinkle half a cup of Arm & Hammer Baking Soda across the bottom. You can add a layer of unscented clumping cat litter to soak up moisture, or place a Moso Natural Air Purifying Bag beside the liner. Then fit a fresh odor-control bag. This is the easiest way to deodorize a trash can for the long term, and baking soda for trash can odor is still the cheapest option.

Mistakes to Avoid When You Clean a Smelly Trash Can
- Mixing bleach with vinegar or ammonia. This can create toxic fumes. Use one disinfectant at a time and rinse between them.
- Skipping the drying step. A damp can smells again within days.
- Using boiling water on plastic. It can warp the can and the lid. Hot tap water is enough.
- Washing only the inside. Odor clings to the rim, lid, and exterior too.
- Skipping gloves. Garbage residue carries bacteria, so protect your hands.
How to Keep a Trash Can From Smelling Again
A little routine goes a long way. These habits mean you will not have to clean a smelly trash can nearly as often.
- Drain liquids before bagging. Pour off leftover liquids and double-bag meat, fish, and diapers.
- Freeze smelly scraps. Keep meat trimmings in the freezer until collection day.
- Rinse weekly. A two-minute rinse prevents residue from building up.
- Choose a lid that seals well. Our guide to trash can lid types explains which designs hold odor in best.
- Keep outdoor cans in the shade. Heat speeds up bacteria. A hidden spot or one of the outdoor trash can enclosures we recommend keeps bins cooler and tidier.
- Stop animals from tipping the can. Spilled waste leaves a sticky residue, so learn how to keep animals out of trash cans.
