The gasket, or seal, in your fridge door is responsible for maintaining cold air in and warm air out of the cooling compartment. In case it gets dried out, whether due to age or disuse, it wo not seal correctly, leading to premature and condensation food spoilage.
Seal It Up
Vaseline, or petroleum jelly, can soften a dried gasket so it will form a fantastic seal around the door of your fridge. The Vaseline will not repair damage such as cracks or tears, but if the damage is small, it might create a temporary seal until the gasket can be replaced. To use Vaseline or petroleum jelly, gently wash the gasket with warm water and dish soap. Rinse and dry it, and then spread a thin layer of Vaseline above all visible parts of the gasket. Manage the gasket gently while cleaning and also apply the Vaseline so you don’t accidentally cause any harm; a dried-out gasket can tear easily.
