TL;DR
Clean a dog crate in four passes: empty it, soak the tray, scrub the bars and door, then handle the floor and wall around it. Most crate smell comes from the pan seam and the floor under the crate, not the bars. Enzyme cleaner is the right tool for urine, and everything has to dry fully before bedding goes back in.
Empty the crate all the way
Take out the bedding, the pad, the toys, the water clip, and the tray. A crate cleaned around its contents is a crate that still smells the next day.
Start the bedding in the wash while you work so it dries on the same timeline as the crate. Our guide to washing the crate pad and bedding covers the tag rules and the drying trap that makes a clean pad smell musty.
Then move the crate itself if you can. Sliding it out gives you access to the floor underneath, which is almost always dirtier than the crate. If the crate is too heavy or your dog is anxious about the change, tip it up on one side instead and work in halves.
How do you clean a crate tray?
Rinse the tray outside or in a tub, then soak it in hot water with dish soap for ten to fifteen minutes. Scrub with a stiff brush, paying attention to the seam where the floor of the tray meets the raised lip. Rinse until the water runs clear and dry it completely before it goes back.
That seam is the whole problem. Urine and drool run to the lowest point, dry in the corner radius, and build a layer no wipe-down reaches. A brush with some stiffness matters more than any particular cleaner here.
Plastic trays scratch, and scratched plastic holds odor. If a tray has gone chalky and rough and still smells after a proper scrub, replacing it is cheaper than fighting it. Metal pans hold up better but can rust at a chipped edge, so dry those quickly. There is more on pan-specific care in cleaning kennel floor pans and trays.
Bars, door, and latch
Wire crates look easy and hide grime in three places: the top and bottom of each vertical bar where it meets the frame, the door hinge, and the latch mechanism.
Wipe the bars with hot soapy water and a cloth, running the cloth along each bar rather than across it. Use an old toothbrush on the latch and hinges. If the crate has a plastic-coated wire finish, avoid abrasive pads, because scratched coating peels and then rusts underneath.
Fabric and soft-sided crates get vacuumed first, then spot cleaned according to the tag, then dried fully with the door open. Travel crates that fly have their own rules and hardware; see cleaning a travel or airline crate.
The floor zone is where the smell lives
Most people clean the crate and are surprised the room still smells. The reason is the floor.
Vacuum the whole footprint of the crate plus about two feet in every direction, including into the baseboard gap. Then treat the floor for its material. Sealed hardwood and laminate get a damp mop only, never a wet one, since standing water at a crate corner is a real cause of cupping and dark staining. Tile gets a neutral cleaner and attention to the grout lines, which are porous and hold odor. Luxury vinyl plank cleans easily but its seams admit water, and steam is off the table because heat can lift the wear layer.
For urine that has soaked in, an enzyme cleaner is the only category that actually breaks down the odor compounds instead of covering them. It needs contact time and it needs to stay wet while it works. Our explainer on how enzyme cleaners work on urine covers the dwell time people usually cut short.
Wipe the wall and baseboard behind and beside the crate too. Dogs shake, drool, and lean, and that lower wall band collects a film that no floor cleaning touches. Keeping baseboards on a regular schedule makes a bigger difference in a pet room than in almost any other part of a house.
What cleaners are safe for a dog crate?
Hot water with dish soap handles most of it, and an enzyme cleaner handles urine. Rinse anything you use, because a crate is a surface your dog licks, lies on, and breathes against for hours.
Skip strongly scented products and skip essential oils. Many oils are toxic to cats and birds are extremely sensitive to airborne fumes, which matters in a multi-pet house. Source: ASPCA Animal Poison Control Center.
Never mix bleach with ammonia, vinegar, or any acidic cleaner. Urine contains ammonia compounds, so pouring bleach on a soiled tray is a genuine gas hazard, not a hypothetical one. If you do use a diluted bleach solution on a plastic tray, ventilate the space, keep the dog out of the room, rinse thoroughly with clean water, and dry before use.
Drying and putting it back together
Air dry every part with the door open before anything goes back in. A crate reassembled damp smells worse in two days than it did before you cleaned it.
Put the tray back first, then the pad, then the toys. Give the pad the squeeze test in the middle; if it is even slightly cool and heavy, it is still wet.
How often should a crate be cleaned?
A quick daily pass, a weekly wash, and a full strip-down monthly works for most dogs.
| Frequency | What it covers |
|---|---|
| Daily | Remove hair and debris, shake out the pad, wipe any spills |
| Weekly | Wash the pad, wipe bars and door, rinse the tray, vacuum the floor zone |
| Monthly | Full soak of the tray, latch and hinge detail, floor and wall treatment |
| Immediately | Any accident, any illness, any bedding with urine on it |
Puppies, senior dogs, and dogs recovering from illness need a faster cycle. So does any crate in a garage or covered porch, where damp air slows drying and mildew gets a foothold.
When the smell is not a cleaning problem
If a crate develops a strong smell fast, or your dog starts having accidents in a crate it used to keep clean, call your veterinarian. Sudden changes in urination, loose stool, or a distinct new odor are medical information, and cleaning does not treat, prevent, or cure anything.
The same applies to a persistent musty smell in the room rather than the crate. If you suspect mold on a wall or under flooring, that is a remediation job for a specialist trade, not a scrub-harder job.
FAQ
How often should I clean my dog crate?
Do a quick daily pass, a weekly wash of the pad and tray, and a full strip-down monthly. Clean immediately after any accident or illness. Puppies, senior dogs, and crates kept in damp garages or porches need a faster cycle than an indoor crate for a healthy adult dog.
Why does my dog crate smell even after I clean it?
The smell is usually in the tray seam, the floor under the crate, or the wall behind it rather than on the bars. Urine wicks into grout, floor seams, and baseboard gaps. Clean the whole footprint with an enzyme product and give it real contact time.
Can I hose down a dog crate outside?
Yes for wire and plastic crates, as long as you can dry them fully afterward. Avoid it for anything with fabric panels, foam, or electronics. In wet Oregon months, a hosed crate left outside overnight often comes back damper than it started, so dry it indoors with airflow.
Is bleach safe to use on a dog crate?
A properly diluted bleach solution can be used on plastic and metal, but only with ventilation, a thorough clean water rinse, and full drying before the dog returns. Never mix it with ammonia, vinegar, or any acid, and remember that urine itself contains ammonia compounds.
What is the best cleaner for dog urine in a crate?
An enzyme cleaner made for pet urine. It breaks down the compounds that cause odor instead of masking them, which is why perfumed sprays fail. It needs to stay wet on the surface for the time the label states, often ten minutes or more, to do anything at all.
How do I get hair out of the crate corners?
Vacuum with a crevice tool first, then use a rubber squeegee or a damp rubber glove to gather what is left. Hair clings to plastic with static, so a slightly damp tool collects it far better than a dry one. Finish with a wipe-down before the pad goes back.
A clean crate in a room with a dirty floor still smells like a kennel, which is why the floor zone matters as much as the crate does. If you would rather hand the floor zone off, see house cleaning. Every home is different, so the real number depends on size, condition, and what you want covered. Get a quote and we will walk you through it.
