Taking Care of a Mirro Pressure Cooker
Caring for your Mirro pressure cooker does not have to be hard
to do. Also, caring for your cooker properly can help to extend
the lifetime of your cooker.
If you've recently purchased a Mirro cooker then you need to wash
it with hot soapy water and dry it well before using it for the
Before using your cooker you need to remember to never beat a potato
masher, spoon, etc, against the pressure cooker's rim, this action
can cause a dent or mar that will potentially cause it to not seal
The inside of your cooker needs to be cleaned after each use. An
easy way to clean it is to run warm water into it as soon as the
food is removed from the cooker. When you are ready to clean it,
use warm soapy water.
Do you have hard water stains in one of your Mirro pressure cookers?
To remove them you will need:
soap filled steel-wool pad
cream of tartar
To clean: boil 1 quart water of water with 2 teaspoons of the
cream of tartar. Allow this solution to boil in the pressure cooker,
with the cover(lid) OFF, for a few minutes. Allow the water to cool.
Clean interior with the steel-wool pad and allow to dry.
(You can substitute a the cream of tartar solution with a solution
made of equal parts water and vinegar).
To clean the exterior, clean with silver polish occasionally. To
keep your exterior from dulling never soak or cover the pan in water
and do not wash in the dishwasher.
After each use of your pressure cooker you will want to remove
the gasket from the lid. Wash the gasket in warm soapy water, rinse,
and dry thoroughly. Then put the gasket back into the cover so that
your cooker is ready for its next use.
You will want to be sure to always wash the cooker's cover after
each use. Run hot water around the openings in the handle to keep
the lift pin assembly free from food particles and grease that could
keep your cooker from operating correctly.
-Keep in mind that if moisture stays inside of the handle, the steam
may not appear around the handle during the next use. Mirro's User
Manual states that this is normal.
After washing and rinsing the cooker's cover, and before using
it, hold the cover up to the light so you can see through the vent
tube. If you cannot see light through the vent tube then it may
be blocked. To unblock your cooker's vent tube, carefully run a
wire or small pipe cleaner in and out of the vent tube to be sure
that the tube is clear and unobstructed. Rinse again in hot water.
Your pressure control will typically stay clean as the steam that
comes out of the cleaner serves as almost a self cleaning for the
pressure control. However, it will not harm the control if you choose
to wash it in warm, soapy water. Be sure to rinse thoroughly after
To store your Mirro pressure cooker: store it with the cover off,
or upside down on the cooker. Do not store with cover and
gasket tightened on. Storing it with the cover tighted
on can cause a vacuum seal inside of your pressure cooker making
the cover nearly impossible to remove.
