A visitor told me the other day that she'd always been told to wash fruit in hot water, to remove germs. Hot water would surely affect the fruit, I'd never heard of that before.
I never wash fruit, unless it's visibly grubby. IMO, we are far too "protected" from a few germs these days, my grandma used to say that you have to eat four pounds of dirt in your lifetime (but preferably not all at once).
