5.4 Dirt removal
There are various reasons for stains. The food that is burned and stuck in the cooker
should be cleaned with detergent and non-metallic dishwashing wire by heating under
the water. Extreme heating of the stainless steel causes brown, blue, yellow or green
stains. When you use the pressure cooking in high temperatures, fading can appear.
Fading will disappear when you use the pressure cooker at normal temperatures. If they
are not lost, they can be removed by using lemon juice. Depending on the density of
the fading, cleaning process should be repeated with vinegar. Usage and washing water
usually causes round, brown and transparent stains. The pressure cooker is made of
18/10 Cr/Ni stainless steel, therefore, it is stainless. Calcium carbonate (limescale) or
salt causes round and white stains. Do not wash the cooker in a dishwasher or reduce
the amount of cleaning products and salt usage. For example, to prevent the water
and salt stains, add salt or water to the food when it is boiling. You might be living
in an area that has hard water. Therefore the fading can also be removed with acidic
acid (concentrated vinegar) or lemon juice. Depending on the density of the fading, the
cleaning process should be repeated with vinegar or citric acid.
5.5 The lid of the pressure cooker cannot be opened.
• If there still is pressure in the cooker, the safety lock is on. Try again after a while.
• Cooling down slowly might produce the vacuum in the cooker. Try opening the lid by
turning the cooking valve fully to the steam discharge position. Never force the lid to
open.
• Cooking valve might be clogged. Wait until the pressure cooker is fully cooled down.
