Washing Fruit

    I've been negligent in washing my (USA) apples & grapes before eating them. I know you're s'posed to, but somehow I wonder just how much washing them removes anyway.

    I know there's soaps that you can get that are designed for rinsing fruit, but I don't want to go that far if I don't have to.

    What is the frosty-looking coating on red grapes? Simple rinsing doesn't take it off, it seems somewhat waxy. If there's pesticides in that, no simple washing will get rid of it.

    It's even on wild grapes, so I've always thought it was a slight oxidating of the skin, something produced by the grape skin, or 'dead skin cells'.

    I just wash off the layer of dust that sometimes can blanket a fruit. Other than that I don't know what the hype is all about.

    Well, the hype is about pesticides and preservatives that are sprayed on fruit so they don't go bad in transport or on the shelf.

    Hmm I have been reading that the 'dust' on grapes is mostly yeast

    Blueberries have a very similar "coating".

    I bought some apples recently that had a very waxy coating on them, wouldn't wash off.
