Top posting. One solvent that does not bother solenoids, and is an
excellent cleaner is transmission fluid. It does not bother rubber tubing
either, and is not very expensive. I do remember tape punches, and wish
you pleasure with yours.

One irradiated spray bottle full of it, from your local hardware store and
auto parts store should suffice.
