Thank you for the response. I no longer have the flux or solder. The layout is wired and complete and I did not keep any of it. I am also unable to clean the connections without completing tearing up all the track and ballast. I do know the solder and flux was old. Got it off of my pap's tool bench. So whatever was popular back in the 80's and 90's is probably what it was. The track in the picture is some leftover track I had in a drawer and noticed the rust on it!!!! Its approximately 7 years old from the time of soldering.
