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

By Priya Sharma · October 13, 2025

Immediate Action (first 5 minutes)

Mayonnaise is an absolute nightmare for pressure cookers. I learned this the hard way after hosting a summer potluck where someone dumped a half-empty jar of Hellmann's into my 6-quart Instant Pot Duo. The oil and egg emulsion immediately clung to the silicone sealing ring. If you are staring at a greasy mess right now, don't panic. You have a crucial 5-minute window before the oils set into the porous silicone.

Grab a silicone spatula and gently scrape off the thick globs. Do not rub it in. Rubbing pushes the lipid molecules deeper into the microscopic pores of the lid's gasket. Next, take a dry paper towel and blot the remaining residue. I keep a roll of Bounty Quilted Quicker Picker-Ups in my kitchen specifically for oily spills like this. They absorb the fat without smearing it across the stainless steel inner pot.

Mayonnaise is essentially an emulsion of oil, water, and egg yolk. The lecithin in the egg yolk acts as a binder. When this hits the warm, porous silicone of your Instant Pot ring, the emulsion breaks down. The water evaporates quickly. This leaves the soybean oil and egg proteins trapped deep inside the microscopic valleys of the rubber. If the mayo has already dried or cooked onto the anti-block shield, skip to the soaking steps below. Time is your enemy here.

What You'll Need (tools/products)

I've tested dozens of degreasers over my 12 years of reviewing kitchen appliances. Cheap dish soaps just won't cut it for emulsified oil stains. You need heavy-duty surfactants to break down the soybean oil and egg yolks found in standard mayonnaise. Here is my exact toolkit for tackling this greasy disaster.

Dawn Platinum Powerwash Dish Spray ($6-$8): This is non-negotiable. The spray foam clings to vertical surfaces like the anti-block shield.
Arm & Hammer Baking Soda ($4 for a 16oz box): Acts as a gentle abrasive and odor absorber.
Heinz White Vinegar ($3-$5): Cuts through the lingering fatty film.
OXO Good Grips Deep Clean Brush Set ($15-$20): The narrow bristle head fits perfectly under the steam release valve.
Zwipes Microfiber Cleaning Cloths ($12 for 12-pack): Essential for wiping down the stainless steel without leaving lint.
Genuine Instant Pot Sealing Ring 2-Pack ($12-$15): Always keep a backup.

Let's look at how these cleaning agents perform against stubborn mayo stains.

Product	Best For	Cost	Effectiveness
Dawn Platinum	Fresh oil stains	$6-$8	9/10
Baking Soda Paste	Odor removal	$4	8/10
White Vinegar	Hard water & film	$3-$5	7/10

I'll be honest, buying the branded Instant Pot rings feels like a cash grab. But the third-party silicone rings I bought on Amazon for $8 warped after three pressure cycles. Stick to the official $12-$15 packs.

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

Getting mayo out of the crevices requires patience. I spent three hours last Tuesday perfecting this exact sequence on my Instant Pot Pro Plus. Follow these steps precisely to save your silicone gasket from smelling like a rancid deli sandwich.

Step 1: Completely Disassemble the Lid

Pop the silicone sealing ring out of the lid track. Pull it firmly but evenly so you don't stretch the rubber. Next, remove the anti-block shield. You just pinch the metal tab and pull it down. If your model has a removable steam release pipe, unscrew it. Mayo loves to hide in these tiny mechanical gaps. Don't forget to pull the small silicone cap off the float valve pin.

Step 2: Pre-Treat with Dawn Powerwash

Spray the Dawn Platinum Powerwash directly onto the silicone ring and the underside of the lid. Let it sit for exactly 4 minutes. The enzymes need time to break the oil-water emulsion. Don't let it dry out. If your kitchen is particularly warm, spray a little extra on the thickest globs.

Step 3: Scrub the Crevices

Take your OXO Good Grips brush and scrub the anti-block shield. Use a circular motion. You'll see the mayo turn into a milky white lather. Rinse the brush frequently in hot tap water (around 120°F). Wipe the lid's metal surface with a damp Zwipes microfiber cloth.

Step 4: Apply a Baking Soda Paste

Mix 3 tablespoons of Arm & Hammer baking soda with 1 tablespoon of warm water. Smear this thick paste all over the silicone sealing ring. The baking soda pulls the trapped oils out of the silicone pores. Let it sit for 15 minutes. This step is crucial if you plan to cook a sweet dessert like cheesecake in the pot later.

Step 5: The Vinegar Rinse

Rinse the baking soda off under hot running water. Spray the ring lightly with undiluted white vinegar. It will fizz aggressively. This chemical reaction lifts the final microscopic fat particles. Rinse one last time and shake off the excess water.

Step 6: Steam Clean the Inner Pot

Pour 2 cups of cold water and a splash of vinegar into the stainless steel inner pot. Secure the clean lid. Set your Instant Pot to the 'Steam' function for 5 minutes. This sanitizes the main chamber and blasts hot steam through the valves, clearing out any hidden mayo splatters.

Alternative Methods (2-3 backup methods)

Sometimes the standard wash just doesn't work. Maybe the mayo sat in the pot over a long holiday weekend. I've had to rescue my sister's Instant Pot Ultra after she left a potato salad in it for four days. Here are my backup strategies when the grease refuses to budge.

The Freezer Trick for Hardened Mayo

If the mayonnaise has dried into a crusty yellow shell, don't scrape it. You'll scratch the stainless steel. Put the entire inner pot and the lid (without the electronic base, obviously) into your freezer. Leave it for 45 minutes. The extreme cold causes the fats to contract and become brittle. Pop it out and flex the silicone ring. The frozen mayo chunks will shatter and peel right off.

Dishwasher Sanitize Cycle

The silicone ring and the metal lid are technically top-rack dishwasher safe. I only do this as a last resort because high heat can degrade the silicone over time. Place the ring and shield on the top rack of your Bosch or Whirlpool dishwasher. Add a Cascade Platinum pod. Run the heavy cycle with the 'Sanitize' and 'Extra Dry' options enabled. The 155°F water will melt the oil away. Just be prepared for the ring to absorb a slight detergent smell.

Lemon Juice and Sunlight Deodorizing

Getting the stain out is half the battle. The lingering smell is the real enemy. Squeeze the juice of two large lemons into a bowl. Submerge the clean silicone ring in the juice. Place the bowl outside in direct sunlight for 3 hours. UV rays naturally bleach the yellow turmeric stains often found in mayo, while the citric acid neutralizes the egg odor.

Prevention Tips

I hate cleaning the sealing ring. It's tedious and messy. After ruining my third gasket with a spicy mayo pulled pork recipe, I implemented a few strict rules in my kitchen. These habits will save you hours of scrubbing.

Buy Color-Coded Rings: Instant Pot sells a 2-pack with one blue and one red ring. I use the red one exclusively for savory, high-fat foods like mayo-based marinades. The blue one stays strictly for rice and desserts.
Use a Splatter Guard: When sautéing ingredients coated in mayonnaise, place a standard 9-inch mesh splatter screen over the pot before the pressure builds. It catches the heavy oil droplets.
Deglaze Immediately: If you are using mayo as a binder for spices before pressure cooking, add your broth right away. Scrape the bottom with a wooden spoon to prevent the oil from baking onto the metal.
Wipe the Rim: Before locking the lid, run a damp paper towel around the stainless steel rim. A single drop of mayo on the rim will get baked into the silicone seal during the pressure cycle.
Host Smart: When hosting a Super Bowl party and making buffalo chicken dip, serve it from a separate ceramic slow cooker. Keep your Instant Pot reserved for the main dishes to avoid cross-contamination of heavy dairy and oils.

FAQ (3-5 questions)

Can I use bleach to clean the Instant Pot silicone ring?

Never use bleach on the silicone sealing ring. The harsh chlorine breaks down the rubber polymers, causing microscopic tears that will lead to steam leaks during your next cook. Stick to oxygen-based cleaners or the baking soda method I outlined above.

Why does my Instant Pot still smell like mayo after washing?

Silicone is highly porous and absorbs volatile organic compounds from strong-smelling foods. If the smell persists, the oils have penetrated too deeply into the gasket. You will need to replace the ring entirely or try the lemon juice and sunlight trick.

Is it safe to cook with mayonnaise in an Instant Pot?

Yes, but you must thin it out with a liquid like broth or water. Mayonnaise is too thick and fatty to generate the steam required for pressure cooking on its own. If you don't add enough thin liquid, you will trigger the dreaded 'Burn' notice on the digital display.

How often should I replace the Instant Pot sealing ring?

Instant Pot officially recommends replacing the sealing ring every 12 to 18 months. However, if you frequently cook high-fat foods or notice the ring is stretched, discolored, or leaking steam, replace it immediately. I buy a fresh 2-pack every January to start the year right.
