Why does my trash can still smell after I clean it?

Because the odor is bacteria in the residue film, not the trash. A quick wipe leaves that film on the plastic, especially in the bottom seam and around the lid, so the smell returns within a day. Scrub every surface with hot soapy water, use an enzymatic cleaner to digest the residue, and dry the can fully.

Does bleach get rid of garbage can odor?

Bleach kills some bacteria but does not break down the organic residue that holds the smell, so the odor usually comes back. It also only masks while the chlorine smell lingers. An enzymatic cleaner removes the actual food source. We never use chlorine or ozone in homes and do not recommend them for this.

The can is clean but my kitchen still smells. What now?

The odor has spread into the room. Trash liquid splashes the wall, floor, and cabinets behind the bin, and porous surfaces like grout, drywall, and baseboard hold it after the can is clean. At that point you need to deodorize the room at the source, a job we handle in 1 to 4 hours.

Garbage Can and Trash Can Smell: How to Get Rid of It

Food & Kitchen · By Odor Removal Experts · Updated June 2026 · Cleveland and Northeast Ohio

To get rid of garbage can smell, you have to remove the rotten residue and the bacteria feeding on it, not spray over the top. Empty the can, scrub it with hot soapy water, rinse, and let it dry fully. For a can that has soaked up months of liquid waste, an enzymatic cleaner breaks down the organic film that holds the smell, which bleach and air freshener never touch. That handles the can itself.

The harder problem is when the smell has left the can. Trash liquid splashes the wall behind the bin, and warm air carries it into cabinets and soft surfaces. Once a rotten odor settles into a kitchen or a garage, scrubbing the can does nothing, because the source is now in the room. That is where a professional treatment earns its keep, and it is the most common garbage can complaint we hear across Greater Cleveland, OH.

The short answer

Empty the can, scrub every surface with hot soapy water, rinse, and dry it fully. For a bin that soaked up months of liquid waste, an enzymatic cleaner breaks down the organic film that bleach and air freshener never touch. If the room still smells after the can is clean, the odor has spread into walls, cabinets, and floors, and the room itself needs treating.

The smell is bacteria in the residue film, not the trash.
Liquid pools in the bottom seam, lid, and rim channel.
Enzymatic cleaner removes the source; bleach and ozone only mask.
If the room still smells, the odor has left the bin.

Why your trash can smells bad even after you empty it

An empty can can still reek because the odor is not the trash. It is the bacteria living in the residue coating the inside of the bin. Meat juice, dairy, coffee grounds, and food scraps leave a thin organic film on the plastic, and bacteria break that film down into the gases you smell. Heat speeds it up, so a bin in a warm kitchen or a closed garage gets worse fast in summer.

Liquid also pools where you never look, and a quick wipe skips these spots so the smell comes right back:

The bottom seam
The underside of the lid
The channel around the rim

The fix is to reach every surface and break down the film, not to cover it with a scented liner.

How to clean a smelly garbage can the right way

A proper clean reaches every surface and digests the film, so the smell does not just return.

Empty and move the can. Take it outside or to a drain where you can rinse freely.
Scrub every surface. Use hot water and dish soap with a stiff brush that reaches the corners a sponge misses, then rinse and pour out all the water.
Switch to an enzymatic cleaner. If it still smells after a normal scrub, apply an enzymatic cleaner to digest the organic residue ordinary detergent leaves behind, and let it sit for the time on the label.
Dry the can fully. A wet can grows new bacteria fast, so dry it completely before use.

Skip ozone and chlorine bombs

We never use ozone or chlorine bombs for this, and we do not recommend them at home. They are harsh, they can damage finishes, and they only mask. Green, enzymatic treatment removes the source, which is the only thing that keeps the smell from returning.

When the smell has spread into the kitchen or garage

If you have cleaned the can and the room still smells, the odor has moved into porous surfaces that hold it long after the can is spotless:

Grout on a tile floor
Drywall and baseboard behind the bin
Cabinet interiors
Any nearby rug or mat

At that point you are deodorizing a room, not a bin. This is what we treat. We find the surfaces holding the odor, treat them at the source, and run HEPA and activated-carbon air scrubbing to pull the smell out of the air. For a garage, we also check for liquid that has run under shelving or into a floor crack. Most jobs finish in 1 to 4 hours, same or next day, and the result is a neutral room, not a perfumed one. We work across Akron, Canton, Mansfield, Youngstown as well.

How to keep the smell from coming back

A few habits keep the film from building back up.

Keep wet waste out of the dry bin by bagging food scraps, draining liquids, and rinsing recyclables
Add a layer of baking soda to absorb moisture between cleanings
Rinse the can monthly and run an enzymatic treatment every couple of months so the film never builds up
If a smell keeps returning to the same spot no matter how often you clean, the source is usually in the room, not the bin
