Short of that, pickle can be neutralized with baking soda, then
more baking soda added until it's more or less a solid, then put it
in a container and throw it away as solid waste in your garbage.
Why do you think that toilet bowl cleaner (sodium bisulfate) needs
to be "neutralized? Do you pour baking soda into your toilet bowl
and dry it and spoon it out before removal to a landfill? I don't.
I just flush it. What do you use for a toilet in the meantime?
Is swimming pool water "neutralized" at the end of the summer? How
about all of those hot tubs? What about foods that are pickled
As for the bluish color that my pickle acquires, I have no doubt
that it is copper. We have even heard from someone that recycles
this copper sulphate for granulation. I doubt that I lose a full 1
gram of copper in my pickle over a one year period, as this is
material that has been etched from only the surface and very near
the surface of my work. I strongly suspect that a lot more copper is
leached from the copper plumbing in my house by the wate rthat I
purchase from the local water authority.
I would agree that one needs to be very careful of what one throws
into their septic system, but before we carry on with more
discussion of "proper sodium bisulfate disposal", it might be smart
to find out what the facts really are. In the end, the landfills are
filling up pretty quickly and it seems silly to just add more
chemicals than are necessary (baking soda and kitty litter come to
mind, not to mention the newspapers and plastic bags to wrap it all
in) to the mix.
