The can of Goof Off I have here is labeled Professional Strength. Probably
all the ingredients aren't listed, but it does say on the can that it
contains acetone and xylene. It also says on the can that it's for use on
all metals.
I sprayed some on a couple of old aluminum antenna elements and on my
aluminum ladder, wiped it around and let it dry. 15 munutes later no damage
to the aluminum was seen.
If there is some concern, just test it on the inside of the cabinet before
using it on the outside.

I would try "Goof Off" http://www.goof-off.com/ Home Depot, Lowes, &
many other places sell it.
Contains alcohol, anti-freeze and an acid that may etch aluminum.
A lot of the industrial ink jet printers don't use an ink at all; many are
polymers. Think toner.
Try acetone, toluene or MEK (methyl ethyl ketone). All are solvents that
will attack various plastics but not etch aluminum. The really nasty
heavy-duty paint removers are generous with the MEK.
