(Maybe I should not I do all this because I'm in Pakistan and these are grapes right off the vine.)

    You can guess what happened: my wife thought my HCA was vinegar, and used went through the process using HCA instead of vinegar.

    Looking at the HCA MSDS, it's clear that you shouldn't drink HCA, but neither does it seem to be really bad stuff (sodium sulfite and sodium bisulfite).

    Obviously I can toss the grapes and start all over again, but I'm curious about the fundamental question if grapes rinsed in diluted HCA would be harmful to one's health. Any thoughts?
    this is the one case where i would not cut washing time in half after HCA.

    Many years ago we made a hiking trip in the mountains. On the last day we had no drinking water left. But a small amount of petrol in a beer bottle. Everybody was said, this ist petrol, be carful. But you guess what happened nevertheless. (Nothing real fatal happened, but it was not enjoyable for the person who drunk a bit of petrol)

    Since this time I never store chemicals in food containers.

    Once I eat a small amount of henna which my wife left in the kitchen. I thought it was spinach. Tasts bitter.

    HCA Great for food

    I use it over sliced apples to keep them from turning brown and mushy.

    Ever get the feeling of deja vu http://www.apug.org/forums/forum37/6...-sulphite.html?

    Murray Minchin's post in that thread (#6) is one of my all time APUG favourites.

    HCA is primarily sodium sulfite, a food preservative. It might also have other chemicals as well, but I would trust Koch's response. Rinse briefly in pure water. - David Lyga

    Why is your wife rinsing grapes in the darkroom, or why are you storing photochemicals in food bottles in the kitchen without telling your family? That is the real question here.
    Nice work. You have a very talented computer.

    Well we saturate out french fries (and battered fish) in neat vinegar and then eat them (fish and chips is an English delicacy).

    The live beer we drink is pumped from barrels in the pub cellar and the lines (pipes) are left for an interval with sterilizing fluid, sometimes daily, they pump the sterilizing fluid out with water or beer so the first pint may have some contaminant, which they discard... Think they use sodium metabisuphite...

    Pint anyone?

    How many times has it been discussed:food bottles reused in the darkroom vs bottles purchase for chemical storage both being safe.

    I only handle wet photo chemicails with rubber gloves and only use PQ soups and Rodinal, with powders face mask.

    The cyclic hydrocarbons are pretty dangerous, e.g. if you are sensitized by metol you will be sorry.
