How to Protect Rubber fridge's Door Gaskets

Lubricating gaskets such as those on refrigerator doors prolongs their life.

Lubricating gaskets such as those on refrigerator doors prolongs their life.

Door gaskets -- whether on a car, refrigerator or even a sliding patio door -- are subject to drying out, rotting or cracking over time. Gaskets prone to weather extremes, such as those on car doors, can age even more quickly if not properly maintained. Lubricating these gaskets with petroleum jelly or weather stripping lubricant will help prolong their lives, keeping them flexible and able to seal properly for years to come


Wipe down the entire door gasket using a sponge dipped in clean soapy water. Wipe until all dust, dirt or other particles have been removed. Rinse with a clean damp sponge. Dry the gasket using paper towels.


Apply a grease-based lubricant, such as petroleum jelly, by dipping a paper towel into the container, then rubbing the lubricant onto the door gasket. Coat the entire gasket thoroughly, wiping excess off one area and onto another. If using a spray lubricant, carefully spray down the entire gasket, making sure the liquid gets into the folds of the gasket as well, if the gasket has folds.


Repeat Step 2 for all the other exposed gaskets -- for instance, the other doors and trunk if you are working on a car, or the freezer door if you are working on a refrigerator.


Repeat the cleaning and lubing process once a year, or more often if dealing with a gasket exposed to the elements.

Things You Will Need

  • Soapy water

  • Sponge

  • Paper towels

  • Petroleum jelly or weatherstrip lubricant


  • While maintaining a door gasket, look around for other things that may have gaskets as well. Lube them all and let that be a routine, so you can be sure every gasket potentially needing lubrication has been lubricated.

  • Consult the manual of your refrigerator, car or whatever other items feature door gaskets to learn the manufacturer's recommendations for gasket lubrication.


  • If a gasket on a refrigerator door or freezer is stiff, cracked and clearly not sealing the way it used to, the gap is a source of energy loss. Replace the gasket to help cut energy costs. Cracked door gaskets on vehicles can also be replaced.
