If you ever bring fresh fruit home and notice a few fruit flies in your house, guess where those came from…
Also, having grown up on an apple farm, I can tell you for sure, washing fruit as soon as you bring it home strips off the fine coating of natural wax and makes the fruit spoil more quickly. Its fine to wash just before you eat it, but washing it out of pure OCD is a good way to spoil fresh fruit.
TIL you can soak freshly-picked blackberries to get larvae out ( www.kuow.org )
