I swear if you read the manual its in there! but I am just working off my shit memory
I snagged this from pressure cooker tips.com.
How to restore a Gasket?
Restoration on the gasket is still possible if it has simply started running out, yet if the gasket has splits, replacement of the gasket is necessary.
Get a hold of the gasket in one location and carry it down in the direction of the center of the cover to launch it from its place. Laundry the gasket with soap as well as water. Rinse off the gasket as well as air-dry it for a few minutes.
Very finely layer the gasket with vegetable oil to recover it from moisture loss. Wipe off any kind of excess oil. Put the gasket back into the cover for storage space or for use. Affix it securely into the groove of the lid ensuring that it is appropriately positioned.
As the gasket (rubber or silicone) grows older, it might become completely dry or weak. Soak it in hot water for 10 to 15 minutes before using it. Nevertheless, this is not a permanent option. You require to replace it immediately.
Oh and by the way I checked my manual and it did not mention this trick, my guess is it may not be 100 percent fool proof and someone could sue them if it didn't work
