[Elecraft] Organic Rosin Core Solder

[Don Brown]

Hi

This sounds like water soluble flux. This stuff needs to be cleaned off as 
soon as possible or it will cause corrosion. Normally is is cleaned in 
distilled water in a special washing machine. I would suggest placing your 
circuit boards in the dishwasher and run it through the normal cycle. 
Alcohol, acetone or other petroleum based cleaners will not work on this 
flux it is designed to be cleaned with water. This stuff is difficult to use 
without the proper techniques. Use the recommended rosin core flux and 
cleaning is a non issue.
