Does anyone have any strong feelings one way or another as to
whether boric acid/alcohol, Prips or commercial products like
Cupronil compare in terms of reducing firescale? Does one seem to
work better with gold vs. silver?
If anyone has been unable to locate boric acid at a pharmacy, you
can also find it at the grocery store or hardware store in the
insecticide section. It is sold as powdered roach killer. You should
be able to get a 1 pound container for $2-$3.00 US.
Cheers and thanks, -Mike
