Was: WKM silver cleaning solution
I renamed the thread so that it reflects what we are discussing.
I'm not only looking for safer alternatives of what's considered
the industry standard, but also thinking about our environment.
No argument from me there. It is an interesting problem which touches
many aspects of any fabrication process. If we are torch soldering,
as an example, we need the joint to be clean and kept clean while we
do the join. How we get there can be approached in many different
ways, 2 extremes could be 1) mechanically abrade to remove oxides and
sulfides and then degrease with a soap and use a substance like borax
to keep new oxides from forming during the soldering. 2) Use a very
strong aggressive flux and skip the cleaning steps and go directly to
Needless to say the choice is a personal one for the one man shop
and often made by accountants and process engineers in a
manufacturing facility. It really does come down to dollars and cents
for the manufacturer, Make 1 million widgets a year, save 10 cents in
labor and you are talking of one hundred thousand dollars profit made
Being Green does cost money often and is a choice one has to make
often on a personal and on a professional level.

methods of doing what we do every day and maybe come up with some
