Keep this step-by-step guide handy for some post- feast cleaning.
Fill the cooker with some water.
Add 2-3 sliced onions inside. For larger stains, add skins of several onions.
Place it on the stove and cover it with a lid. Make sure you don’t seal the pressurized lid.
Switch on the stove and allow the onions to boil for 20-30 minutes.
Take the cooker off the stove and allow it to cool.
Add 3 drops of Vim dishwash gel and scrub the stains with a scrubbing pad.
Rinse it with clean water and there you go; your pressure cooker is now ready for another feast!
