Wash the berries in a diluted vinegar bath (1 cup vinegar plus 3 cups water) and spin them dry in a salad spinner lined with paper towels until they are completely dry. Store the cleaned berries in a sealable container lined with paper towels, leaving the lid open a little to allow moisture to escape.
The vinegar destroys bacteria and mold spores on the berries, helping them stay fresh longer. According to Lifehacker, this method extends the shelf life of berries by days, sometimes even weeks.
