>I would be interested in knowing what acid is listed on the Duzall label.
Duzall Flux is very nasty stuff. The primary ingredient is Zinc Chloride.
It can cause severe burns and may be fatal if swallowed!
BUT the good news is that it will allow you to solder to about anything
except Aluminum and Magnesium. I find it especially useful for soldering
to Stainless Steel and it works well on Chrome, Monel, Cast Iron plus
all of the usual stuff but which has been corroded.
But use caution and follow the label--it is no more dangerous than climbing
towers or working with high voltage!
