How to Clean a Trash Can? | A Step-By-Step That Actually Works

Cleaning a trash can is one of those chores everyone puts off until the smell forces the issue. Yet the process has only a handful of steps, and each one matters. Skip the drying step and you’ll get mildew under the new liner; miss the wheels and the grime just spreads. The full routine below takes about twenty minutes, and you can knock it out with items you already own. If you’d rather not bend over a bin every week, our roundup of the best electric trash can options covers hands-free models that take most of the contact out of the job.

What You Need Before You Start

Gather everything first so you aren’t hunting for supplies mid-scrub. Most of this is already under your sink.

• Long-handled scrub brush or sponge
• Dish soap or a degreasing cleaner
• Hose with a spray nozzle or a pressure washer
• Rubber gloves
• Baking soda (only if odors persist)
• Disinfectant spray (optional, but recommended)

Wear those gloves. If the can has held anything questionable, add eye protection, closed-toe shoes, and a mask for strong odors. Work outside on a lawn or driveway where soapy runoff won’t damage anything, since you’ll be rinsing directly onto the ground or into a drain.

The Cleaning Process: Step by Step

The order matters — cleaning a trash can with junk still inside is just redistributing the mess. Follow these steps in sequence.

1. Empty the can completely. Tilt it over and shake out any loose debris, then check the bottom for stuck-on bits.
2. Rinse with the hose. Hit the inside walls, the bottom, and the lid to knock off loose grime before you add soap. A pressure washer at low pressure works great here, but a hose nozzle does the job too.
3. Scrub with soapy water. Squirt dish soap directly into the can, add a little water, and scrub every interior surface with your long-handled brush. Pay special attention to the bottom rim where liquids pool.
4. Rinse thoroughly. This step is easy to rush, but soap residue left behind will attract new dirt and can leave a filmy layer. Rinse until the water runs clear.
5. Don’t forget the outside. The lid, handles, and wheels collect as much grime as the inside. Scrub them with the same soapy water and rinse well.
6. Let it dry completely. Turn the can upside down with the lid off and let it air-dry overnight in the sun. Sunlight also helps neutralize odors naturally. Never add a new liner to a damp bin — trapped moisture breeds mildew and undoes your work.

The whole cycle takes 15 to 20 minutes of active work, plus drying time. It’s the drying, not the scrubbing, that most people skip, and it’s the one step that actually prevents the next round of smells.

How Do You Get Rid of Trash Can Odors?

A targeted treatment handles it.

Sprinkle a generous layer of baking soda across the bottom and up the sides after cleaning, then let it sit for at least an hour. The baking soda absorbs lingering odors while it sits. Rinse it out before you add a new liner, or leave a thin layer in the bottom as a proactive odor absorber.

For disinfection, spray the inside, outside, and lid with a disinfectant labeled for the job. Leave it for 30 seconds to sanitize, or a full 2 minutes to disinfect, then wipe it away with a cloth.

What Not to Do: Common Mistakes

Most of the errors people make are small, but they compound into a can that never quite stays clean.

• Relining before the can is dry. A wet bin under a fresh liner is a mildew factory. Wait overnight.
• Skipping the lid and wheels. These surfaces touch your hands and your floor. If they’re dirty, the whole can is dirty.
• Using harsh chemicals on stainless steel. Acidic or alkaline cleaners can pit and dull the finish. For metal bins, rinse with clean water and a mild soap, then dry with a soft cloth.
• Rinsing soap off too fast. Foam rinsing away isn’t the same as the surface being clean; the residue stays behind.

For commercial or public bins, the bar is higher. Use an EPA-registered disinfectant with labeled kill claims and follow the contact time on the product label exactly, rather than guessing.

A clean trash can is mostly about consistency. Give the bin a proper rinse every couple of weeks and a full scrub monthly, and you’ll never face the dreaded lid-lift moment again. When the chore itself becomes the problem, an electric can with a sealed lid and deodorizer takes most of the grunt work out of the routine entirely.
