Tested: How to Get Soy Sauce Out of Instant Pot Fast

By Priya Sharma · September 29, 2025

Immediate Action (First 5 Minutes)

Grab a towel. Wipe it fast. Soy sauce is incredibly ruthless on porous surfaces and unsealed metals. When you're rushing to get dinner on the table after hosting a massive dinner party and accidentally knock over the glass Kikkoman bottle, that dark, salty liquid will seep into every microscopic crevice of your appliance. The high sodium and amino acid content in soy sauce means it doesn't just stain; it can actually cause microscopic pitting in stainless steel if left to dry completely.

If you have kids who love helping in the kitchen and inevitably knock over the sauce bottles while you're making stir-fry, you know the panic. Your first move should always be a damp microfiber cloth. Do not use paper towels. Paper towels just smear the dark caramel coloring around the plastic housing and push it deeper into the seams. I keep a dedicated stack of Amazon Basics 12x12 inch microfiber cloths right next to my 6-quart Instant Pot Duo for this exact reason. Blot the spill immediately, working from the outside edges toward the center to prevent the stain from spreading across the white exterior.

What You'll Need

I've tested dozens of cleaning products on my own appliances over the last decade. You don't need expensive, specialized chemicals to figure out how to get soy sauce out of instant pot components. You just need the right combination of mild abrasives and degreasers. Here is my exact toolkit for tackling these stubborn, salty stains.

Product	Purpose	Estimated Cost
Bar Keepers Friend Soft Cleanser (13 oz)	Removes baked-on stains from the stainless steel inner pot without scratching.	$4.50 - $6.00
Dawn Platinum Powerwash (16 oz)	Cuts through the sticky, salty residue on the exterior plastic housing.	$5.50 - $7.00
Mr. Clean Magic Eraser (4-pack)	Lifts set-in soy sauce shadows from the white plastic base and lid.	$8.00 - $10.00
70% Isopropyl Alcohol	Dissolves sticky drips on the internal heating element safely.	$3.00 - $4.00

I recommend the liquid version of Bar Keepers Friend over the powder. The soft cleanser clings to the vertical walls of the inner pot much better, giving the oxalic acid time to break down the dark soy proteins. This isn't the cheapest option compared to generic baking soda, but it saves you at least twenty minutes of aggressive scrubbing.

Step-by-Step Removal

After hosting a dinner party and making a massive batch of soy-braised short ribs, my inner pot usually looks like a crime scene. The soy sauce caramelizes onto the metal during the high-pressure cook. Here is the exact 5-step process I use to restore my Instant Pot to factory condition.

Step 1: The Vinegar Boil-Out

Don't start scrubbing right away. Pour 2 cups of warm water and 1 cup of standard 5% acidity white vinegar into the stained inner pot. Secure the lid, set the valve to sealing, and run it on Manual High Pressure for exactly 5 minutes. The acidic steam loosens the baked-on soy sauce crust. Let the pressure release naturally for 10 minutes before opening.

Step 2: Scrub the Inner Pot

Dump the vinegar water and rinse the pot. While the stainless steel is still warm and damp, squirt a generous ring of Bar Keepers Friend Soft Cleanser around the interior. Use a non-scratch silicone sponge to scrub in circular motions. I'll be honest, this takes a little elbow grease around the rim where the soy sauce boils over, but the stains will lift within 3 minutes of scrubbing.

Step 3: Clean the Exterior Housing

Spray Dawn Platinum Powerwash directly onto the exterior plastic base. Let it sit for 60 seconds to break down the salty grease. Wipe it away with a damp microfiber cloth. If you have the white model, you might notice a faint brown shadow left behind. Wet a Magic Eraser, squeeze out the excess water, and gently buff that shadow away. Don't press too hard, or you'll dull the plastic finish.

Step 4: Tackle the Heating Element

If soy sauce dripped down the side of the inner pot and onto the heating element inside the base, you must clean it before your next cook. Unplug the machine and let it cool completely. Dip a cotton swab in 70% isopropyl alcohol and gently rub the sticky, burnt soy spots. The alcohol dissolves the sugar and salt without introducing water to the electronics. Let it air dry for 30 minutes.

Step 5: Wash the Silicone Ring and Lid

Pop the silicone sealing ring out of the lid. Wash it in the sink with hot water and Dawn dish soap. Use a toothbrush to scrub the anti-block shield and the steam release valve, as soy sauce foam loves to hide in these tiny crevices. Rinse everything thoroughly and let it air dry on a dish rack.

Alternative Methods

Sometimes you don't have Bar Keepers Friend in the pantry, or you're dealing with a stain that's been sitting there for weeks. I've tested these backup methods when I was in a pinch, and they genuinely work.

The Denture Tablet Soak

This is my favorite lazy hack for the stainless steel inner pot. Drop two Efferdent denture cleaning tablets into the pot and fill it with hot tap water. The effervescent action and mild bleaching agents lift the dark soy sauce stains without any scrubbing. Let it sit for 4 hours or overnight. I usually do this before I go to bed, and by morning, the pot is spotless.

Baking Soda and Hydrogen Peroxide Paste

For stubborn exterior stains on the plastic housing, mix 3 tablespoons of baking soda with 1 tablespoon of 3% hydrogen peroxide. Stir it into a thick paste and apply it directly to the soy sauce stain. Cover it with a piece of plastic wrap to keep it from drying out. Wait 45 minutes, then wipe it away with a damp cloth. The peroxide gently bleaches the dark caramel coloring out of the porous plastic.

Lemon Juice and Coarse Salt

If you want a completely natural approach for the inner pot, cut a lemon in half and dip the cut side into coarse kosher salt. Use the lemon as a scrubber, pressing firmly against the stained metal. The citric acid breaks down the soy proteins while the salt acts as a gentle abrasive. It smells amazing, though it does take about 10 minutes of continuous scrubbing to get the same results as commercial cleaners.

Prevention Tips

Figuring out how to get soy sauce out of instant pot parts is useful, but preventing the mess in the first place is much easier. I've adopted a few strict habits in my kitchen to keep my appliance looking brand new.

Use a Silicone Splatter Guard: When reducing soy-heavy sauces on the sauté function, place a 9-inch silicone splatter screen over the top. It lets steam escape but catches the dark, salty bubbles that try to escape.
Pour Over a Sink: Never pour soy sauce directly from the bottle while the inner pot is sitting inside the hot base. Always pull the pot out, or at least move it to the sink. Drips are inevitable, and wiping soy sauce off the heating element is a nightmare.
Buy Color-Coded Silicone Rings: Soy sauce will permanently stain a clear or light-colored silicone ring brown. I keep a dedicated dark red ring specifically for savory, soy-heavy meals like teriyaki chicken and beef stew. This way, the visual stain doesn't bother me, and I reserve my clear rings for yogurt and desserts.
Wipe the Rim Before Closing: Before you lock the lid, run a damp paper towel around the top rim of the inner pot. Soy sauce splatters often dry on the rim during the sauté phase, which can compromise the seal and cause sticky leaks down the outside of the pot during pressure cooking.

FAQ

Will soy sauce ruin the stainless steel inner pot?

Soy sauce won't permanently ruin your stainless steel inner pot, but the high salt content can cause pitting if left for weeks. I've seen tiny rust spots form on my 8-quart model after forgetting to wash it for a month. Always rinse it out immediately after cooking to protect the metal finish.

How do I get the soy sauce smell out of the silicone sealing ring?

The porous silicone absorbs the strong umami odor, making your next batch of yogurt taste like beef stew. I bake my rings on a cookie sheet at 250°F for 20 minutes to evaporate the trapped oils. If that fails, soaking the ring in a 50/50 mix of white vinegar and water overnight usually does the trick.

Can I put the Instant Pot lid in the dishwasher if it has soy sauce on it?

You can put the lid on the top rack of your dishwasher, but you must remove the silicone sealing ring and anti-block shield first. The dishwasher's high heat can bake the soy sauce proteins into those removable parts, making them impossible to clean later.

What if soy sauce dripped onto the heating element inside the base?

Never submerge the base in water, as this will destroy the internal electronics and void your warranty. I use a cotton swab dipped in 70% isopropyl alcohol to gently dissolve the sticky residue directly on the metal element. Let it air dry completely for at least two hours before plugging the appliance back in.
