Step 2.
Wash the gasket gently in soapy water with a sponge or soft brush.

Step 3.
Rinse the gasket, and allow it to air-dry.

Step 4
Inspect the gasket carefully. If it has nicks or cracks that indicate damage, you must replace it.

Step 5
Apply a thin coat of vegetable oil to restore the gasket if it simply looks dry. Wipe away excess oil.

Replace the gasket in the clean lid for storage or use. Insert it into the groove in the lid, pushing it in all the way around the lid until it is properly seated.
