Will propane flame melt copper brazing?
Not exactly. Others have said that caustic soda run through a
recirculating pump will eventually eat through the crud, but I have no
pump to do this. So I propose to try just putting the exchanger into
a heated bath with caustic soda in it. I have no idea if this will be
successful or not, therefore I thought I would solicit opinions on the
incineration idea.
