Kuhn Rikon DUROMATIC COMFORT Instruction Manual page 63

The SI valve (main safety device) must always be correctly fitted in
the lid when using the pressure cooker (= spring visible on the
inside of the lid). Never remove this valve for cleaning!
Do not wash the pan, lid, protection cap or gasket in a
dishwasher.
Never remove stains or burned-on marks with abrasive means such
as with knives, steel wool or copper cloths. Instead, soak in hot
water with a little detergent until stains can be easily removed with a
soft brush, sponge or cloth.
The printed protection cap in particular should only ever be cleaned
with a damp cloth (never use abrasive cleaners, bleach or SWISS
CLEANER).
Do not use any corrosive agents like Javel water for cleaning.
Remove obstinate scaling (white spots) with a few drops of
vinegar, lemon juice or SWISS CLEANER. (See section 16)
If the pan has become discoloured from overheating,
then we recommend the use of SWISS CLEANER
paste.
If the lid is difficult to turn, then apply a light film of cooking oil to
the rubber gasket.
When storing, place the inverted lid on the pan so that the rubber
gasket inside the lid is free and does not become deformed.
