    What's the difference between Amazon's citric acid and the suppliers? Amazon can ship but they can't?

    I used the Amazon citric acid the other week, and used almost the entire 2lbs bag. I'm not sure how much you're supposed to use for an acid wash on a single 8-inch membrane, but it only got the pH down to 3.2, and I thought you need to get it to ~2 for a proper acid wash.

    I'm not sure what the difference is between the maple companies and the Amazon stuff.

    I never heard that the citric acid could not be shipped, just the lye soap. I got my last batch shipped from Amazon, didn't have time to go pick it up. Try a health food store if you have one nearby.
    Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
    Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
    Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
    After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.

    It can be shipped. Just has to be in an approved tamper proof package and Probley another 100 requirements. It’s a white powder. So usually draws attention when being shipped. That’s what I was told anyways a couple years ago when I tried to buy my RO soap and storage solution powder from CDL and get them to ship it.
    I just buy it bulk at health food stores. It’s way cheaper that way. And it’s food grade. I usually buy 10 lbs of it at a time.

    Just another example of how the criminal element hurts the honest.
