After dipping, rinse thoroughly or soak in tub of cold water to remove bleach residue.

Cut off off any injured areas where bleach solution soaked into the flesh. You can see how far it soaks in. I cut a little more than the affected area.

Washing large quantity of apples in tub will bruise them as they bang into each other. They shouldn't be washed any sooner than a day before they are used. I often wash the night before I press.

One of the great things about cider is that it can use sub par fruit that would never store, and might even be visual unpalatable. The bulk of the pomice comes from feral apples (I just can't see grinding the beautiful clean fruit from our cared for trees) We shake trees out and scoop up the drops. Sooty blotch, mild scab, minor insect damage, fresh bruising....all fine. Nothing that has been rodent chewed, old bruising, or shows insect frass. And of course nothing that has come in contact with deer feces.

We give apples a quick soak in fresh water, the move them into another bin full of water and roll the around with each other as a scrub. This pulls off road dust or any other minor dirt/mud
They then get pulled and dropped into a milkcrate. At this point your looking for any fruit that is still dirty or that should not have been picked up to begin with.
The milk crate gets a final rinse from the hose and in they go to the grinder.
Water in tubs is frequently changed.

Are we grinding up some bugs....sure, does anybody care....no. Everyone we know begs cider from us as it blows the socks off the sweet insipid stuff from the commercial orchards. The fact that's it organic is nice too.
To be fair to the commercial places, they are required to pasteurize, and that's hard on flavors....but most of them are running single variety table fruit and that tends to be pretty boring from the start in cider.

If your using a juicer I would probably be a lot fussier, as you will be rendering the skin into the finished product. But with a traditional crushing grind and press that's not the case.

With care the risk is very small, but everyone needs to decide what they feel is acceptable risk in this life
