Did you know that one of the first thing to wear out of a refrigerator is the rubber door gasket? So, with this simple tip, you can protect the gasket from cracking, drying, and mildew. Just apply a very thin coat of Vaseline petroleum jelly. By this simple procedure, you are preforming a preventative for the cracking, drying, and mildew! It also improves the seal!

If you are having trouble with ice build-up on the heater coils in the back of an older fridge and are having to go through the lengthy process of removing the food and shelves to defrost with a hair dryer -- a little Vaseline may be all you need!
Never use bleach, diluted or undiluted, to clean refrigerator seals as it breaks down the rubber. I used to, but after 18 months I had to replace the seals.
