I saw this idea on the Dr. Oz show and gave it a try. Mix three parts water to one part vinegar. I used 3 cups of water and 1 cup of vinegar. Add this to a large bowl and then add the fresh fruit. Swish it around and clean it well. This will kill any bacteria that results in moldy fruit. Place fruit in a colander and rinse with cool water. Place fruit on paper towels and blot dry, then place fruit in a container that has been lined with a paper towel, seal with airtight lid and refrigerate. This should extend the life of your fruit. I used this on strawberries, blackberries, blueberries, grapes and cherries.
