Misenware
Use & Care

Quickstart Guide

New to Misenware? A few quick tips to get you started.

Separate the bodies. Misenware is jam-proof, so it won’t stick together when you stack it. But because the bodies come wrapped in protective paper, they can be hard to separate at first. If yours are stuck, gently pry them apart with a wooden spoon, or put them in the freezer for 30 minutes and try again, pulling them apart from the short side.
Remove all packaging and labels. Wash containers and lids in warm, soapy water, rinse thoroughly, and dry completely (or just toss them in the dishwasher). Then you’re ready to go.
Open the steam vent before pressing the lid onto the body. With the vent closed, trapped air can keep the lid from sitting flush. You may notice that pressing one side down makes the other side lift.
Close the vent once the lid is seated to make your Misenware leakproof.
Sealing hot food? Leave the vent open while it cools. This prevents a vacuum seal that can make the lid very difficult to remove, or even cause the glass to shatter.
Microwaving? Always leave the vent open to release excess steam.
To unseal, open the steam vent first, then work the lid open along the silicone edge. Don’t force it, since the glass can crack under pressure. If it won’t budge, contact our support team.

The rule of thumb: Vent open for closing, heating, cooling, and opening. Vent closed only once the lid is seated and you want a leakproof seal.

Cleaning & Care

Dishwasher safe: Both containers and lids are dishwasher-safe. Top rack is recommended for the lid.
Detergent: Avoid detergents containing chlorine or citrus additives, which can degrade stainless steel over time.
To prevent sticking: For cooking tasks, preheat the container and add a small amount of oil before adding food.

How to Remove Odors From Your Misenware Lid

The silicone gasket on your Misenware lid can retain odors from strong-smelling foods like garlic, fish, and spices. The most effective way to remove odors is the oven method:

Wash the lid with a grease-cutting dish soap (like Dawn) and warm water.
Dry the lid completely.
Preheat your oven to 350°F.
Place the lid on a baking sheet and bake for 30 minutes.
Remove from the oven and let cool until you can handle it comfortably. Most or all of the odor should be gone.

Microwave Use

Yes, you can use Misenware in the microwave. Here's how to do it right:

Wattage and time limits: The container and lid are safe at 1000W for up to 10 minutes at a time, and 1100W for up to 5 minutes at a time. Check the sticker inside your microwave door or your microwave's manual to confirm the wattage.

If your microwave is over 1100W, do not microwave Misenware, even if you lower the wattage manually.
One container at a time: Only microwave one container at a time.
Never microwave empty: Always have food or liquid inside before microwaving. Without food to absorb the energy, the microwave heats itself, which can cause damage.
Lid on or off: The lid is microwave-safe. Leave the steam vent open to release excess steam. The lid gets extremely hot so use oven mitts when removing it, and use caution as steam may escape.
Let hot food cool before sealing the lid vent. After microwaving, leave the steam vent open and allow the container to cool for a few minutes before closing the lid fully. Sealing the lid over hot food traps hot air inside — as the container cools, that air contracts and creates a vacuum that can pull the lid inward. A vacuum-sealed lid is very difficult to remove, and forcing it can cause the glass to crack or shatter.

If your lid is stuck, do not force it. Ensure the steam vent is open, then let the food cool until the lid comes off easily.
Keep it centered: Sit the container centered on the turntable with clearance on all sides. Avoid contact with the microwave walls, metal rack, or turntable plate—this can cause sparking or burn marks.
No cutlery or foil: Do not place cutlery or foil inside the container while microwaving.
Not for 915 MHz microwaves: All standard home microwaves in the U.S. operate at 2.45 GHz. Do not use Misenware in 915 MHz commercial or industrial microwaves.
Dented containers: If your container somehow sustains major denting, stop using it in the microwave. It can still be used for cold storage, prep, or oven use.

Oven & Grill Use

Oven & toaster oven: Container body is oven-safe up to 932°F/500°C. Lid is oven-safe up to 450°F.
Air fryer: Safe in toaster-oven-style air fryers. Avoid basket-style air fryers — Misenware's size may restrict airflow in some basket units and cause overheating.
Grill: Container body is grill-safe. Do not place the lid on the grill because it's only heat-safe to 450°F and grill temperatures typically exceed that.
Stovetop: Not recommended. The container shape makes it more susceptible to deformation from direct stovetop heat.

Fridge & Freezer Use

Fridge & Freezer: Misenware is fridge- and freezer-safe. Store food directly in Misenware, seal with the lid, and put it straight in.
Freezer to oven: The container can go directly from the freezer to the oven. The tempered glass lid is not freezer-to-oven safe, so defrost in the fridge first if you want to heat with the lid.
Freezer to microwave: The container can go directly from the freezer to the microwave. The tempered glass lid is not freezer-to-microwave safe, so defrost in the fridge first if you want to heat with the lid.
Note: Misenware is not airtight. The steam vent in the lid is a vent, not a pressure valve, so it's not suited for long-term airtight dry storage. For everyday food storage in the fridge or freezer, it performs great.

Labeling

We tested a range of markers and pens on Misenware. Every brand’s formula is a little different, so before writing on your Misenware with any pen, test a small spot on the bottom of the container first. Anything not on the list below is use-at-your-own-risk.

These are the three pens we’ve tested and can stand behind:

Expo Dry Erase Marker (our top pick)
Writes on steel, glass, and silicone. Dries quickly and cleans off easily. Note: Because it’s so easy to remove, it can smudge if you rub against it.

Souper Cubes Water-Based Paint Pen
Writes on steel, glass, and silicone and holds on well with minimal smudging once dry. Note: doesn’t write well on cold containers, so let your Misenware come to room temperature first. A little harder to clean off than dry erase, but still removable.

Lazgol Wet Erase Marker
Holds on well and resists accidental smudging. Note: doesn’t write well on cold containers or on glass, so it's best for the steel body only.

If a pen won’t come off:

Use a small amount of Bar Keepers Friend and a little steel wool under hot water. It should come off quickly.

Common sense note: Don’t expose any ink or tape to heat (oven, grill, microwave). We didn’t make those products and can’t speak to how they’ll respond to heat.

On the Go

Misenware is leakproof, meaning it passes upside-down and sideways leak tests with water, oil, and tomato sauce at all durations. Throw it in a tote without worry.

Frequently Asked Questions

Yes! Misenware is lab-tested and safe in 1000W microwaves for up to 10 minutes at a time, and in 1100W microwaves for up to 5 minutes at a time.

The common "no metal in the microwave" rule was never about all metal, it was about poorly designed metal with thin edges, sharp points, or right-angle corners that concentrate electromagnetic energy and cause a spark. Misenware is built with thick 304 stainless steel and rounded corners that reflect microwave energy safely. We've tested this extensively across all three container sizes at multiple wattages and durations.

NOTE: Make sure Misenware doesn't come in contact with the microwave's metal plate, rack, or interior walls which can cause sparking or burn marks. Do not microwave cutlery or foil with Misenware, as this will cause sparking.

Misenware containers are safe in 1000W microwaves for up to 10 minutes at a time, and 1100W for up to 5 minutes at a time. Check the sticker inside your microwave door or your microwave's manual to confirm your oven's wattage. Do not use in 1200W microwaves or 915 MHz microwaves.

Yes. The lid is microwave-safe at 1100W for up to 5 minutes at a time, and at 1000W for up to 10 minutes at a time. Leave the steam vent open when microwaving to release excess steam and cook efficiently. Note that the lid gets extremely hot after microwaving, so always use oven mitts or a towel when removing it, and use caution when removing lids, as steam may escape.

This usually happens when the lid is sealed over hot food and then allowed to cool. Hot air trapped inside contracts as it cools, creating a vacuum that pulls the lid inward. To release it: open the steam vent first, then let the food cool until the lid comes off easily. Do not force it — the glass lid can crack or shatter under pressure.

Check that the steam vent is open. When the vent is closed, placing the lid on the container can trap air inside and create resistance that prevents the lid from seating evenly. Opening the vent allows the air to equalize, then once the lid is fully seated, you can close the vent to seal the container.

No. Only microwave one container at a time.

Yes. The container body is oven-safe up to 932°F/500ºC. The silicone-rimmed glass lid is oven-safe up to 450°F. For cooking above 450°F, remove the lid or leave it ajar.

The stainless steel container can go from the freezer to the oven. It passes freezer-to-oven testing at 500°F (without lid) with no warping or deformation. The lids are not freezer-to-oven safe due to the tempered glass lid.

Yes. The container body is grill-safe. Do not place the lid on the grill, as it is only heat-safe to 450°F and grill temperatures typically exceed that.

Yes. Yes. As long as the lid is properly sealed and the vent is fully closed, Misenware passes upside-down and sideways leak tests with water, oil, and tomato sauce at all time durations, so you can throw them in a tote without worry.

Yes. Both the container and the lid are dishwasher-safe. We recommend washing the lid in the top rack, as it is slightly gentler. Avoid detergents containing chlorine or citrus additives, which can degrade stainless steel over time.

No. Stainless steel doesn't stain, hold onto food odors, or leach chemicals into your food, even after repeated use at high heat. This is one of its biggest advantages over plastic and silicone containers.

Note: if you use stainless steel in a very high-heat oven without food inside repeatedly, you may see surface discoloration, but this doesn't affect performance.
