Most fruit salad can last about three days, you can keep it up to five days, but I wouldn't keep it longer than that. I like to take leftover fruit salad (if it has only sugar on it) and add it to yogurt,or you could add it to some ice cream, maybe make a milk shake with the fruit. The best thing you can do is, make only what you will use as you need it.
