[Heathkit] Cleaning up after Soldering and kit building.

[Bwana Bob]

Once I used a can of Radio Shack flux solvent on an HW-2036. It 
dissolved the flux but also softened the green solder mask on the board, 
turning it into a gooey mess. Fortunately, I was able to clean it up. 
The flux stripper also attacks plastics. These days I remove excess flux 
with a Q-tip dipped in isopropyl alcohol. It's a lot safer.
