Where individual who was American said they wash and scrub their eggs and in some instances wash with bleach.
Why?
The most I have ever done is wipe over with a damp cloth and that is there is loose much on them.
In the US, eggs are washed/cleaned before being packed...it's something they do ( and why their eggs need refrigeration in store).
In the same way, they also over-chlorinate their water supplies - because they think it's better practice.
I certainly don't wash mine unless sometimes they're pretty mucky (a friend has free-range rescue hens) in which case I give them a wipe.
I also just wipe mushrooms (if you peel a chestnut mushroom it loses most of its flavour) but I do trim the bottoms off the stems. That's because when I was a child, they were grown in horse manure - our local riding stables did a roaring trade. :)
I don’t wash, scrub or peel any veg or fruit, or eggs.
The only time I would wash or scrub veg is if it was straight out of the ground and covered in soil.
And I’ve lived to tell the tale ;)
