How to Remove and Clean the Tray From a Metal Dog Kennel

Most metal dog kennels feature a slide-out plastic or metal tray at the bottom — a convenient design that catches urine, food debris, and loose fur. But that same tray is also one of the most overlooked hygiene hazards in your pet's living space. When left uncleaned, it becomes a breeding ground for bacteria, ammonia buildup, and parasites that can cause skin infections, respiratory irritation, and gastrointestinal illness in your dog. In this guide, we walk you through the proper way to remove, clean, and reinstall the tray so your kennel stays safe and sanitary.

Step 1 — Prepare Your Supplies and Workspace

Before you begin, gather the following items:

• A hose with a spray nozzle (or access to a utility sink)
• Pet-safe enzymatic cleaner or a diluted bleach solution (1 part bleach to 32 parts water)
• A stiff-bristle scrub brush dedicated to pet cleaning
• Rubber gloves
• Clean towels or a drying rack

Move the kennel to a well-ventilated area — outdoors or in a garage with the door open. Remove your dog from the immediate area to prevent stress or accidental exposure to cleaning chemicals. Take out any bedding, toys, and water bowls from the kennel before proceeding.

Step 2 — Remove the Slide-Out Tray

Most metal kennel trays are designed to slide out from one side of the crate base. Locate the edge of the tray and gently pull it toward you. Some models have a small lip or handle; others require you to grip the tray edge and lift slightly as you pull to clear the retaining rail.

Common mistake: Forcing the tray at an angle can crack the plastic or bend the metal rails. Always pull straight and level. If the tray feels stuck, check for debris lodged in the rail channel — hair, dried waste, or kibble can jam the mechanism over time.

Design flaw note: Many budget kennels use narrow rails with minimal clearance, making tray removal awkward and increasing the chance of spills. If your tray consistently jams, consider placing a thin layer of parchment paper under the tray to reduce friction and simplify future removals.

Step 3 — Rinse the Tray Outdoors

Carry the tray outside and use a hose to rinse off all loose debris — fur, food particles, and visible waste. Spray from one end to the other to push debris off rather than spreading it around. Use moderate water pressure; high-pressure jets can warp thin plastic trays.

Pay special attention to the corners and edges where urine tends to pool and crystallize. These deposits harbor bacteria and emit ammonia odors that are harmful to both you and your pet's respiratory system.

Step 4 — Scrub With Pet-Safe Disinfectant

After rinsing, apply your chosen cleaner generously across the entire surface of the tray. Let it sit for 3–5 minutes to break down biofilm and kill pathogens.

Using your stiff-bristle brush, scrub the tray in circular motions, focusing on:

• Scratch marks and grooves where bacteria colonize
• The underside edges that contact the rail channel
• Any discolored or stained areas

Why pet-safe matters: Dogs lick their paws and rest their chins on the tray surface. Residual harsh chemicals — even after rinsing — can cause oral irritation, vomiting, or long-term liver stress. Always choose enzymatic cleaners labeled safe for pets, or stick to the diluted bleach ratio above and rinse thoroughly afterward.

Step 5 — Rinse Thoroughly and Dry Completely

Rinse the tray again with clean water until no soap residue remains. Shake off excess water, then dry the tray completely with clean towels or set it on a drying rack in direct sunlight. UV light provides additional natural disinfection.

Do not skip the drying step. Reinstalling a damp tray traps moisture between the tray and the kennel floor, creating the exact warm, humid environment where mold and bacteria thrive. This defeats the entire purpose of cleaning.

Step 6 — Reinstall the Tray

Once the tray is bone-dry, slide it back into the kennel base. Align it with the rails and push gently until it sits flush. Test that it slides smoothly in and out — if it catches, recheck the rail channel for debris.

Replace fresh bedding, return toys and bowls, and your kennel is ready for use. For ongoing maintenance, clean the tray at least once a week for daily-use kennels, or every two weeks for occasional-use crates. Spot-clean visible accidents immediately to prevent staining and odor buildup.

Final Thoughts on Kennel Tray Maintenance

A clean tray is the foundation of dog crate maintenance and pet hygiene. The slide-out design makes this task straightforward — but only if you do it consistently and with the right products. Skipping steps, using harsh chemicals, or reinstalling a wet tray can do more harm than good. Follow this six-step routine weekly, and your dog's kennel will remain a healthy, comfortable space rather than a hidden health hazard.
