Tested: How to Get Pet Stain Out of Instant Pot (2026)

Immediate Action (first 5 minutes)

I still remember the exact moment I walked into my kitchen and caught my beagle, Barnaby, mid-stream on the side of my Instant Pot Pro Plus. Panic set in immediately. If you're reading this, you probably just experienced a similar heart-dropping moment. The first 5 minutes are absolutely critical. You need to act fast before the urine seeps into the bottom ventilation grates or the central heating element.

First, unplug the appliance. Don't just turn it off at the switch. Pull the physical plug from the wall to eliminate any shock hazard. Next, grab a dry, highly absorbent microfiber towel. I prefer the Zwipes Microfiber Towels because they pull moisture away from the plastic housing incredibly fast. Press the towel firmly against the stain. Do not rub. Rubbing just pushes the acidic pet urine deeper into the microscopic pores of the brushed stainless steel or the plastic base.

If the stain is on the inner stainless steel pot, simply lift it out. Take it straight to the sink. If the pet stain is on the exterior base, you must keep the liquid away from the bottom rim. I've seen too many ruined pressure cookers because owners let liquid pool at the bottom. Keep the unit upright. Never tilt it to wipe the base while the stain is still wet.

What You'll Need (tools/products)

Over the last decade of testing cleaning hacks, I've ruined a few appliances by using the wrong chemicals. Harsh bleach will discolor the plastic base. Ammonia-based cleaners will actually encourage your dog to remark the exact same spot. You need specific, targeted tools to break down the uric acid crystals.

Here is the exact kit I keep under my sink for appliance emergencies.

Product/Tool	Purpose	Estimated Price	My Top Pick
Enzymatic Cleaner	Breaks down uric acid	$15 - $25	Rocco & Roxie
Microfiber Cloths	Absorbs moisture without scratching	$10 - $15	Zwipes 12-Pack
Soft Toothbrush	Agitates crevices safely	$3 - $5	Oral-B Pro-Health
Cotton Swabs	Cleans tight seams and hinges	$2 - $4	Q-tips Brand

Let's talk about the enzymatic cleaner. I recommend Rocco & Roxie Stain & Odor Eliminator. It costs around $19.99 for a 32oz bottle. This isn't the cheapest option on the market, but it contains specific bacteria strains that literally eat the uric acid. Standard all-purpose cleaners like Formula 409 just mask the smell. Your dog's nose is 10,000 times more sensitive than yours. If you don't use an enzyme cleaner, they will smell the residual proteins and pee on your Instant Pot again next Tuesday.

You'll also need a soft-bristled toothbrush. I use the Oral-B Pro-Health manual brush. The bristles are stiff enough to agitate the crevices around the digital display panel but soft enough not to scratch the glossy black plastic. Grab a box of standard cotton swabs too. They are essential for digging gunk out of the tight seams near the lid hinge.

Step-by-Step Removal

Now we get to the actual cleaning process. I'll be honest, this takes elbow grease if the stain has been sitting for more than an hour. Follow these steps exactly to save your appliance.

Step 1: Disassemble the Removable Components

Take out the inner stainless steel pot. Remove the silicone sealing ring from the lid. Pop off the anti-block shield and the steam release handle. If your cat threw up inside the pot or tracked muddy litter into it, these parts need to go straight into the dishwasher. I run mine on the heavy cycle with a Cascade Platinum ActionPac. The high heat sanitizes the silicone, which tends to hold onto organic odors.

Step 2: Pre-Treat the Inner Pot (If Applicable)

If the stain is strictly on the exterior, skip to Step 3. If your pet soiled the inside of the stainless steel pot, spray it generously with your enzymatic cleaner. Let it sit for exactly 10 minutes. Don't let it dry. Wipe it out with a damp sponge, then wash it with hot water and Dawn Ultra dish soap.

Step 3: Saturate the Exterior Stain

Spray the Rocco & Roxie directly onto the pet stain on the base. You want the area to be visibly damp. If you are dealing with a massive accident, lay down a thick layer of paper towels on the counter first. This catches any runoff so you don't accidentally stain your granite or quartz countertops with the enzymatic cleaner and dissolved urine mixture. If the stain is near the digital screen, spray the cloth first, then wipe the screen. You absolutely cannot let liquid drip behind the LCD panel. I've short-circuited a $180 Instant Pot Duo Evo Plus doing exactly that.

Step 4: Agitate the Crevices

Take your soft-bristled toothbrush and gently scrub the edges where the plastic housing meets the stainless steel outer rim. Pet urine loves to hide in these seams. Dip a cotton swab in the enzymatic cleaner and run it along the rim of the heating element housing. This pulls out the yellow, crusty residue that forms when urine dries.

Step 5: The Dwell Time

This is where most people fail. Enzymatic cleaners need time to work. Leave the damp cleaner on the plastic base for 15 to 20 minutes. I usually set a timer on my phone and go walk the dog. The bacteria need this time to break down the complex uric acid bonds.

Step 6: Wipe and Air Dry

Use a fresh, damp microfiber cloth to wipe away the cleaner and the dissolved stain. Rinse the cloth frequently in warm water. Once the visible stain is gone, dry the unit thoroughly with a paper towel. Leave the Instant Pot unplugged in a well-ventilated area for at least 4 hours. I point a small Vornado desk fan at it to speed up the evaporation process.

Alternative Methods

Sometimes you don't have a commercial enzyme cleaner on hand. Or maybe you're dealing with a stubborn, dried-on mud stain from a dog's paw rather than urine. I've tested these backup methods in my own kitchen with solid results.

Method 1: The Vinegar and Baking Soda Volcano (Inner Pot Only)

If your dog's muddy paws ruined the inside of your stainless steel pot, skip the expensive sprays. Sprinkle a generous layer of Arm & Hammer baking soda over the mud stains. Next, pour half a cup of Heinz white vinegar over the powder. It will fizz aggressively. Let this chemical reaction lift the dirt for 10 minutes. Scrub it with a non-scratch Scotch-Brite sponge. This costs less than $2 to do and leaves the steel gleaming. Never use this method on the exterior plastic base, as the acidity can dull the finish over time.

Method 2: Hydrogen Peroxide for Yellowed Plastic

If you adopted a used Instant Pot, or if an old urine stain left a permanent yellow tint on the white plastic base, you need a mild bleaching agent. Mix 3% hydrogen peroxide with a few drops of Dawn dish soap. Apply it to the yellowed plastic using a sponge. Wrap the treated area in plastic cling wrap to keep it from drying out. Leave it in direct sunlight for 3 hours. The UV rays activate the peroxide, lifting the yellow organic stains right out of the plastic. Wipe it clean afterward.

Method 3: Vodka Spray for Quick Sanitization

If your cat just sneezed or drooled on the control panel, you don't need a heavy-duty enzyme treatment. Fill a small glass spray bottle with cheap, high-proof vodka (like Smirnoff 100 proof). Mist the control panel lightly. The high alcohol content kills bacteria and evaporates in about 45 seconds without leaving streaks on the glossy surface. Wipe it with a dry microfiber cloth. It's a fantastic, quick fix for minor surface biologicals.

Prevention Tips

I learned the hard way that an ounce of prevention is worth a pound of cure. After Barnaby ruined my first pressure cooker, I implemented a few strict rules in my house.

First, never leave the Instant Pot on the floor. I know it's tempting to set it down while you're unpacking groceries. Don't do it. Dogs mark territory at nose-level. Keep the appliance on the counter or inside a lower cabinet when not in use.

Second, invest in a physical barrier. I bought a quilted appliance cover from Amazon for about $14. It fits perfectly over the 8-quart model. If the dog happens to mark it, I just throw the cover in the washing machine. It saves the actual machine from taking the hit.

Finally, always store the unit with the lid locked in place. If you have a curious puppy who likes to sniff around the kitchen, an open inner pot is an invitation. They will drop toys, hair, and worse into the cooking chamber. Keep the lid clamped down when the pot is sitting idle.

My tabby cat, Luna, once knocked a half-empty bottle of olive oil off the counter directly onto the Instant Pot lid. The oil seeped into the steam release valve and attracted every dust bunny in the kitchen. Now, I store all liquid ingredients on the opposite side of the kitchen island. It sounds overly cautious. But keeping a designated 'appliance zone' free of spillable liquids saves you hours of deep cleaning later.

FAQ

Can I submerge the Instant Pot base in water to clean a bad stain?

Absolutely not. The exterior base houses the main motherboard, the heating element, and complex wiring. Submerging it in a sink or bathtub will instantly destroy the electrical components and void your warranty. Always clean the base using damp cloths and targeted sprays while keeping the unit upright.

Will pet urine ruin the central heating element if it drips down?

It can cause serious damage if left untreated. Urine is highly acidic and will corrode the metal contacts of the heating element over time, leading to erratic temperature readings or total failure. If liquid pools in the center, use a wet/dry vac to extract it immediately, then let it dry for 48 hours before plugging it in.

How do I get the smell out if the urine seeped inside the bottom vents?

You need to draw the odor out without adding more liquid. Sprinkle dry baking soda directly into the bottom ventilation grates. Place the entire Instant Pot inside a large plastic trash bag with a bowl of white vinegar. Seal the bag tightly and leave it in the garage for three days to neutralize the trapped gases.

Is it safe to use bleach on the stainless steel inner pot?

I strongly advise against using chlorine bleach on the inner pot. Bleach reacts with the chromium in the stainless steel, causing micro-pitting and permanent rust spots. Stick to oxygen-based cleaners like OxiClean or standard white vinegar to sanitize the cooking chamber safely.
