I saw a note from John Nolte dating back to 2003 suggesting the use
of Versene for cleaning metal pipes.  I have not been able to find
a suitable source of supply.  Does anyone know of one?

My problem is the minimum order quantity.  Most of the sources offer
five-gallon buckets, or 50-pound sacks, or 1200 pounds, none of which
which are practical for a small application.

I have found a source for disodium EDTA in small quantities, which
I will try.  Tetrasodium EDTA is supposedly better for metal cleaning,
but I can't find it in small quantities.

 [ EDTA apparently is short for ethylene-diamine-tetracetate.

 [ chelate of EDTA, in dry form, and may be used in direct food
