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.
