Awww, I feel for you!
It depends on how long it was in the juice and how wet it was...not too sure, but drying it and scrapping the top layer, as mentioned above, sounds like a good idea - perhaps also spray it down with some alcohol?
I've dropped my stuff in a million things, its not a big deal. let it dry for a while (at least 2 - 4 days) make sure its dry.. take a clean x-cato knive and scrape off the top layer and it should be fine, you dont need to spray it with anything else.. it should be fine (I've droped one of mine into a fish tank before)
let it dry and see what happens. I have a feeling that the texture may be a lot different though, possibly sticky? because of the sugars in apple juice. Although it depends how long it was in there and how wet it got...
