The
lifespan of the average refrigerator is roughly 15 years, but it
would take a miracle for your gasket to last that long. The gasket is
the rubber seal around the door of your refrigerator that is
responsible for keeping cold air in and warm air out. A
properly-functioning gasket is essential in keeping your electricity
bill low, but it is usually the first component to need replacing.
Follow this procedure once every two months to keep yours clean and
effective for as long as possible:

1. Gently
   scrub around the entire gasket with warm water and soap to remove
   dirt and other grime.
2. Completely
   dry the area with a clean towel.
3. Place
   a small amount of Vaseline around the gasket to keep it lubricated
   and prevent it from drying out and cracking.

1. Mix
   one part bleach with two parts water in a spray bottle.
2. Spray
   black spots with the solution and allow to soak for ten minutes.
3. Wipe
   the affected areas and repeat until all visible signs of mold are
   gone. Cotton swabs are good for cleaning small cracks and crevices.
4. After
   all stains are removed, wash again with soap and water to remove all
   traces of the bleach.
5. Apply
   Vaseline on the gasket to prevent it from drying out and cracking.
