You can certainly gently clean the area around the scrapes and punctures; depending on how severe the injuries, the fruit might heal over on its own. I'm not sure if the wax would be good or not--it would perhaps help to prevent some insects and diseases from penetrating the fruit, however, it also would encourage some diseases that might already be in the flesh to develop, as the wax would prevent air circulation around the injury. My best guess would be not to apply the wax, but if you do, make sure the wax is edible and free of fragances and additives, such as pure natural beeswax.
