Over time, heat exposure can contribute to the sealing ring deformation of your pressure cooker. At bedbathbeyond.com, choose from rubber or silicone gaskets to prolong the life of your appliance. Used to keep your pressure cooker airtight by sealing steam between the pan and lid, gaskets typically begin to lose their elasticity between 12 to 18 months. Material wise, new gaskets are commonly made of silicone, specifically because they do not crack easily upon aging, making them a great choice for longevity. And if cleaning is a concern, simply remember to remove the gasket from the lid after every use and hand wash with soapy water. Remember, regular maintenance will ensure that your pressure cooker both stays on top form and stands the test of time. While electric pressure cookers typically look similar on the outside, the construction on the inside makes all the difference. Shop through options of nonstick or stainless steel structures on bedbathbeyond.com where you?ll be able to understand the benefits of each. Nonstick inserts are perfect for cleaning purposes, but the coating can sometimes chip and wear over time, meaning you?ll have to replace the insert. Although stainless steel doesn?t run the risk of wear and tear, you have to be mindful of adding enough oil to the insert to prevent food from sticking.
