Guys,

Per Elecraft's website < http://www.elecraft.com/repair.htm > "The use of
acid-core solder, water-soluble flux solder, or any corrosive or conductive
flux or solvent will void this warranty in its entirety."

Beyond that:

1) Leaded solder is preferable for hand rework as lead-free solder requires
a higher temperature and special tips.  (Your normal leaded solder tips will
not last long if used with lead-free solder.)

2) Mildly activated rosin core flux (RMA) is preferable.

3) "No clean" flux requires a higher activation temperature and if not fully
activated its residue can pose a fire hazard.
