Misenware
Use & Care

Before You Use Misenware

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.

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.

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.
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 400°F. For temperatures above 400°F, remove the lid or leave it ajar.
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 400°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

Before writing directly on your Misenware with any pen, test with a dot on the bottom of the container or on the glass lid, because every brand and marker is different.

We recommend the following ink for writing directly on Misenware:

Dry erase markers
Water-based paint pens
Sharpie Creative Acrylic

If you’d rather use tape to label your Misenware, we recommend masking tape, kitchen tape, or freezer tape.

The following pens are also safe for writing directly on Misenware, though may smudge or require extra scrubbing to wash off:

Wet Erase
Wax Marking Pencils
Liquid Chalk Pens
Steelwriter
Crayon

Do not use permanent markers, paint sticks, or acrylic paint pens other than Sharpie Creative Acrylic.

Duct tape may leave residue, which you can scrub off with hot, soapy water. Painters tape may lose adhesion in the freezer.

Common sense disclaimer: Do not expose ink or tape to heat (oven, grill, microwave). We didn’t make those products so we can’t tell you 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.

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 400°F. For cooking above 400°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 400°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.
