Clean a kitchen trash can by emptying it, washing inside and out with warm soapy water, rinsing completely, and air-drying fully before adding a fresh liner.
The trash can is the one kitchen surface nobody thinks to wash until it smells. A quick wipe between liner changes helps, but a real cleaning — the kind that stops odors at the source — takes about ten minutes and supplies you already own. A clean can also keeps fruit flies away, and it protects the surface under your liner from the residue that eventually seeps through.
Here’s the working method, what to skip, and how to handle a can that still smells after a wash.
Start with an empty can. Take the bin outside or set it in a tub or shower — somewhere a mess won’t matter.
Rinse or hose down the inside to loosen stuck debris, then scrub every surface with dish soap and warm water. Use a sponge or brush with a handle to reach the bottom corners. Pay real attention to the lid, the rim, and the seam where the liner sits — that lip collects drips from every bag you’ve ever lifted out. Rinse thoroughly so no soap film remains, then let the can dry completely upside down with the lid off.
The drying step is the one most people rush. A damp can traps moisture under the next liner, and that trapped moisture is what turns a clean bin sour within days. Give it a few hours or overnight before you replace the bag.
When Soap Isn’t Enough: Deodorizing And Disinfecting
Sprinkle it across the bottom and scrub with a damp sponge, then rinse.
Disinfecting is a separate step from cleaning, and the timing depends on which product you use.
Never mix bleach with other cleaners, and keep the space ventilated.
Steel Cans And Stubborn Messes Need A Softer Touch
Stainless-steel exteriors scratch easily, so skip the abrasive pads and steel wool. Wirecutter’s cleaning experts recommend dish soap and warm water with a nonabrasive sponge for the outside finish.
For a can that fits in your sink, wash it there. For a larger bin, a plastic tub or the shower floor works fine. If the can is truly filthy, do the heavy rinse outdoors with a hose before you bring it inside for the soap scrub.
Once your can is fresh and dry, a quality bin makes the routine easier. If you’re working with an older or smaller model, show which models hold liners securely and resist odor buildup in the first place.
Common Mistakes That Leave A Can Smelling
- Skipping the rinse. Soap residue traps new odors almost as fast as old grime does.
- Relining while damp. Moisture under a fresh bag is the number one cause of recurring smells.
- Forgetting the lid and rim. These collect drips from every bag removal and rarely get washed.
- Using abrasives on steel. Scratches hold bacteria and ruin the finish.
