[Heathkit] OT question on soldering flux

[rbethman]

Ralph,

There indeed is a corrosive component in Paste Flux.  That has been true 
of Dutch Boy flux back into the '70s.

I rarely actually use the paste flux.  I depend on the rosin core solder 
to do the job.

I use a HAKKO soldering mesh to clean the soldering pencils.

The paste flux sees darn near no use.  Only time is when I have a very 
stubborn joint in a tube type circuit.  Then I brush a little coat on 
the joint.
