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

Immediate Action (first 5 minutes)

If your toddler decided the shiny stainless steel insert was a makeshift toilet, or your cat mistook it for a litter box during a chaotic week, don't panic. I've dealt with this exact nightmare. My cat, Barnaby, peed in my 6-quart Instant Pot Duo while I was prepping for a dinner party. You have about five minutes to stop the uric acid from bonding to the metal and silicone. First, unplug the base immediately. Never try to rinse the main heating unit in the sink. Dump the contents into your toilet and flush.

Next, rinse the inner pot with strictly cold water. Hot water cooks the proteins in urine. It bakes the smell right into the steel. Grab a paper towel and wipe out the main base cavity if any splashed over the rim. This isn't the most glamorous cleaning job, but acting fast is the difference between saving your appliance and throwing a $90 machine in the dumpster.

What You'll Need (tools/products)

You can't just use regular dish soap here. Urine contains uric acid crystals that soap simply cannot break down. I've tested dozens of cleaners over my 10 years of professional cleaning, and you need specific enzymatic action to destroy the odor at a molecular level. Here is my exact toolkit for saving a pressure cooker.

Product / Tool	Estimated Cost	Why I Recommend It
Nature's Miracle Urine Destroyer	$14.99	Contains bio-enzymatic bacteria that literally eat uric acid crystals.
Dawn Platinum Powerwash	$5.50	Cuts through the fatty lipids in urine that enzymes leave behind.
Bar Keepers Friend Soft Cleanser	$4.25	Oxalic acid removes the yellow staining from stainless steel.
Gallon Ziploc Bag	$0.10	Creates an airtight soaking chamber for the silicone ring.
Soft-bristle toothbrush	$2.00	Gets into the anti-block shield and steam release valve crevices.

Step-by-Step Removal (4-7 steps)

Step 1: The Cold Water Flush

Take the stainless steel inner pot to your sink. Run cold tap water over the affected area for exactly 60 seconds. Do not use the spray nozzle if it creates a mist. You don't want aerosolized urine particles landing on your clean dishes. Swirl the cold water around, dump it, and repeat three times. This removes the bulk of the liquid waste without setting the proteins.

Step 2: The Enzyme Bath (Inner Pot)

Place the inner pot in your sink or on a protected counter. Spray the entire interior with Nature's Miracle Urine Destroyer. You need to saturate the steel. Let it sit for 15 minutes at room temperature (around 70°F). The enzymes need time to digest the organic matter. I'll be honest, it might smell slightly worse for a few minutes as the bacteria break down the ammonia. Just open a window. After 15 minutes, wash the pot thoroughly with Dawn Platinum and warm water. Rinse until the suds are completely gone.

Step 3: The Silicone Ring Rescue

This is where most people fail. The silicone sealing ring is highly porous. It absorbs odors like a sponge. If the urine sat in the pot with the lid on, that ring is compromised. Pull the ring out of the lid's wire rack. Place it inside your gallon Ziploc bag. Spray the ring heavily with the enzyme cleaner until it's dripping. Seal the bag tight. Leave it on your counter for 24 hours. This airtight environment forces the enzymes deep into the silicone pores. The next day, remove it, wash with Dawn, and let it air dry.

Step 4: Disassemble and Scrub the Lid

Urine splashes. Even if the lid wasn't on the pot, microscopic droplets can land on the underside. Push the anti-block shield off the bottom of the lid using your thumb or a butter knife. Remove the float valve and the silicone cap on the steam release handle. Soak these four small plastic and metal pieces in a bowl of warm water and Dawn dish soap for 10 minutes. Use your soft-bristle toothbrush to scrub the tiny crevices. Rinse them under a strong stream of warm water and snap them back into place.

Step 5: Wiping the Heating Base

Look inside the main cooker base. If you see any drops on the heating element or the silver walls, spray a microfiber cloth with your enzyme cleaner. Never spray directly into the base. Wipe the interior walls and the heating sensor carefully. Follow up with a damp cloth wrung out in clean water to remove any sticky enzyme residue. Dry it immediately with a towel.

Step 6: The UV Sun Bake

Ultraviolet light destroys remaining odor-causing bacteria. Take your clean inner pot, the lid, and the silicone ring outside. Place them in direct sunlight on a patio table for at least 4 hours. I've tested this on my own gear after camping trips, and the sun works miracles on lingering organic smells. Bring them inside only when completely dry.

Alternative Methods (2-3 backup methods)

Backup 1: The Steam-Deodorize Cycle

If you don't have an enzyme cleaner on hand, you can use the machine's own pressure to force odors out. Fill the clean inner pot with 2 cups of white vinegar and 1 cup of water. Toss in three lemon wedges. Lock the lid in place (assuming you've already washed the ring with soap). Set the Instant Pot to the 'Steam' function for 10 minutes on high pressure. The acidic vapor will circulate through the valves and lid, neutralizing ammonia. Let it natural release for 20 minutes before opening.

Backup 2: Hydrogen Peroxide Ring Soak

Silicone rings are notoriously stubborn. If the enzyme soak didn't fully pull the smell out, switch to oxidation. Mix 1 cup of 3% hydrogen peroxide with 1 cup of water in a bowl. Submerge the silicone ring completely. Let it soak for 45 minutes. The peroxide will bubble as it attacks the organic compounds. Rinse thoroughly. I recommend this because it doesn't leave a lingering vinegar smell in your silicone.

Backup 3: Baking Soda Paste for Yellow Stains

Sometimes urine leaves a hard, yellowish scale on the bottom of the stainless steel pot. This is mineral buildup mixed with uric acid. Make a thick paste using 3 tablespoons of baking soda and 1 tablespoon of water. Smear it over the stain. Let it sit for 30 minutes. Scrub it aggressively with a non-scratch sponge. The mild abrasion lifts the scale without scratching your expensive cookware.

Prevention Tips

Nobody wants to deal with this twice. If you have kids who track mud everywhere or pets that jump on counters, you need a strategy. Always store your Instant Pot with the lid locked upside down on the pot. This creates a physical barrier. Cats hate the smooth, curved surface of an inverted lid, and toddlers can't easily pry it open.

If you are using the pot for a meal prep session and step away, put a towel over the open insert. During a 3-day power outage, never use your kitchen appliances as temporary storage bins. I've seen people use dry Instant Pots to hold dirty laundry or pet supplies during emergencies. It's a bad habit that leads to cross-contamination and bizarre cleaning nightmares. Keep it strictly for food.

FAQ

Is it safe to cook in after cleaning?

Yes, absolutely. Once the enzymatic cleaner breaks down the uric acid and you run a hot steam cycle, the stainless steel is completely food-safe. I've cooked dozens of meals in my pot after Barnaby's incident without any lingering smells or health risks.

Can I just put the whole lid in the dishwasher?

You can put the plastic lid on the top rack, but the dishwasher won't remove urine odors from the silicone ring. The heat actually bakes the smell deeper into the porous silicone. Always remove the ring and hand-treat it with enzymes first.

Why does my pot still smell like ammonia when it heats up?

That means microscopic uric acid crystals are still hiding under the anti-block shield or inside the steam release valve. You need to disassemble the lid completely and soak those small parts in a 50/50 vinegar-water solution for 30 minutes.

Will bleach ruin the stainless steel inner pot?

Bleach will permanently pit and corrode your stainless steel insert, ruining the non-stick properties and creating microscopic grooves where bacteria hide. Never use chlorine bleach on any part of your pressure cooker. Stick to oxygen-based cleaners or enzymatic sprays instead.
