Old Oil can turn to glue

I ran into this on a recent machine. A perfect example of what can happen with old oil in a machine that has sat for years. This is where the upper tension release linkage goes on a Singer 221. The upper tension would not release when you lifted the presser foot.
It was "glued" to the mounting surface.
That mess cleaned right up with some lacquer thinner.
