Like any piece of kitchen equipment, you should take good care of your electric pressure cooker if you want to make the most of it. Luckily, cleaning the pot is pretty easy. The outside can get dusty and grimy with food stuff, so just wipe down with a paper towel and spray solution. To avoid lingering odors, keep the lid off the cooker when not in use.
The main part you’ll have to clean is the actual inner pot, where the food goes. You wash this like you would any saucepan, and if you want, you can put it in the dishwasher. If you wash by hand right away, however, you can use the pot again right away, and food doesn’t harden. Plain ol’ soap and hot water is all that’s needed, and a soft sponge, as anything abrasive will scratch the stainless steel.
The lid should also be cleaned, and there are two specific parts on it that can be tricky. There is a metallic “plug” on the inside of the lid that foamy foods can get into. This is the anti-block shield, and it does come off the lid. Don’t twist it, just pull. It may seem like it’s not going to come off, so be careful and pull hard. Clean the inside of the guard, and with a knitting needle (or something else made of metal and thin enough to fit in the hole), just poke inside the tiny valve.
The second part of the lid that should be washed is the silicone ring or, more officially, the gasket. Just rub it with some soap and warm water. If it starts to smell or stain, soak for at least 15 minutes. Gaskets wear out over time, so eventually you have to buy a new one. The last part of the lid that can be cleaned is the float valve. It has a tiny silicone ring on it that can absorb smells and residue, so just pop it off, wipe clean, dry, and fit it back on.
