How to Deep Clean Garbage Cans
If you want a cleaner home, learning how to deep clean garbage cans is one of the most effective maintenance tasks you can do.
A thorough cleaning removes odor-causing residue, bacteria, flies, and the greasy buildup that regular bag changes never fully address.
This guide explains the safest and most effective way to deep clean indoor and outdoor garbage cans, plus how to keep them fresher between cleanings.
Why garbage cans need deep cleaning
Even with liners, trash bins collect liquid leaks, food particles, and dust that settle on the bottom, lid, and sides.
Over time, that residue can produce persistent odors and attract pests such as fruit flies, ants, and maggots.
Deep cleaning helps reduce:
- Bacteria and mold growth from food waste and moisture
- Sticky residue from spilled liquids, sauces, and packaging
- Odors that cling to plastic or metal surfaces
- Stains that make cans look dirty even after the bag is replaced
- Pest attraction around kitchens, garages, and curbside bins
What you need before you start
Gathering the right supplies makes the job faster and safer.
Most garbage cans can be cleaned with common household products.
- Rubber gloves
- Garden hose or access to running water
- Dish soap or all-purpose cleaner
- Baking soda
- White vinegar or disinfecting cleaner
- Scrub brush or stiff-bristle broom
- Microfiber cloths or old towels
- Bucket
- Trash bag for debris
If you are cleaning a metal can, avoid harsh abrasives that may damage the finish.
For plastic cans, test any strong cleaner in a small area first.
How to deep clean garbage cans step by step
1. Empty the can completely
Remove all trash bags, loose debris, and any stuck-on material.
If there is hardened waste at the bottom, use a disposable scraper or paper towel to lift it out before adding water.
2. Rinse out loose dirt and residue
Take the can outside and rinse it with a hose or warm water.
This first rinse helps remove crumbs, soil, and surface grime so the cleaner can work more effectively.
3. Apply soap and scrub thoroughly
Mix warm water with dish soap or use a biodegradable cleaner.
Scrub the interior walls, bottom, lid, rim, and handles, paying close attention to corners and seams where residue collects.
For heavy buildup, let the soapy water sit for 5 to 10 minutes before scrubbing.
A long-handled brush is useful for large outdoor garbage cans.
4. Target odors with baking soda
Sprinkle baking soda directly into the bottom of the can and onto problem areas.
Baking soda helps absorb moisture and neutralize acidic odors from food waste.
For stronger odor control, make a paste with baking soda and water, apply it to stained spots, and scrub after a few minutes.
5. Disinfect the surfaces
After washing, apply a disinfecting cleaner according to label directions.
If you prefer a more natural option, white vinegar can help reduce odor, but it is not a substitute for a registered disinfectant when sanitation is the goal.
Be sure the product you use is appropriate for the material of the can and safe for the surface you are cleaning.
6. Rinse and dry completely
Rinse away all cleaner and loosened grime.
Leaving soap or moisture behind can create a new source of odor, especially in enclosed kitchen bins.
Dry the can with towels or let it air-dry in direct sunlight.
Sunlight can help reduce lingering smells and speeds evaporation.
How to deep clean outdoor garbage cans
Outdoor bins often need more intensive cleaning because they collect road dust, rainwater, and yard debris.
Start by placing the can on a sloped surface or driveway drain area so wastewater can flow away safely.
For outside bins, consider these extra steps:
- Remove the lid and clean the underside separately
- Scrub the wheels and base, where grime tends to collect
- Use a hose with stronger pressure for stuck-on dirt
- Wash the can after trash pickup so it is empty and easier to handle
If the bin has a strong odor from hot weather or spoiled food, repeat the cleaning process and let it dry in the sun before replacing the liner.
How to remove tough smells and stains
Some garbage cans need more than a basic wash.
Persistent odors often come from tiny residue deposits that remain after normal cleaning.
For odors
- Use baking soda after each wash
- Place a small open box of baking soda in the empty can
- Spray the interior lightly with vinegar after cleaning and drying
- Keep the lid open until the can is fully dry
For stains
- Scrub with a baking soda paste
- Use a soft sponge with diluted dish soap
- Try an oxygen-based cleaner on plastic bins if label instructions allow
- Avoid bleach on metal surfaces unless the manufacturer says it is safe
If stains remain on a plastic can, they may be cosmetic rather than sanitary.
Focus on odor removal and disinfection first.
How often should you deep clean garbage cans?
The best cleaning schedule depends on where the can is used and what goes into it.
Kitchen garbage cans usually need deep cleaning more often than outdoor bins because they handle food scraps and liquid leaks.
- Kitchen trash cans: every 2 to 4 weeks
- Bathroom trash cans: monthly or as needed
- Outdoor garbage cans: every 1 to 3 months
- Bins used for pet waste or diapers: more frequently, often weekly
In warmer months, clean more often because heat accelerates bacterial growth and odor.
How to keep garbage cans cleaner between deep cleans
Simple habits can reduce how often you need to scrub your bins.
- Double-bag messy waste like food scraps or pet waste
- Tie bags tightly before placing them in the can
- Wipe spills immediately with soap and water
- Use a liner that fits the can properly
- Sprinkle baking soda at the bottom before adding a new bag
- Rinse recyclable containers before discarding them
- Keep outdoor bins shaded when possible
You can also line the bottom with a few sheets of newspaper or paper towel to absorb drips, though this works best for dry household waste.
Safety tips when cleaning garbage cans
Cleaning garbage cans can expose you to bacteria, sharp objects, and chemical fumes, so basic safety matters.
Wear gloves, keep children and pets away from the area, and avoid mixing cleaning products.
Important safety reminders:
- Never mix bleach with vinegar or ammonia
- Do not use boiling water on thin plastic bins
- Check for broken glass, needles, or other sharp waste before scrubbing
- Rinse outdoor wastewater away from storm drains if local rules require it
- Use products only as directed on the label
When to replace a garbage can instead of cleaning it
Most garbage cans can be restored with a deep cleaning, but some should be replaced.
Cracked plastic, warped lids, and permanently damaged interiors can hold odor and bacteria even after repeated scrubbing.
Consider replacing the can if it has:
- Deep cracks or holes
- Persistent odor after multiple cleanings
- Rust that affects structural integrity
- Missing wheels, hinges, or lid parts
- Heavy staining combined with surface damage
A clean, intact bin is easier to maintain and less likely to attract pests or spread odor through the home.
