Christ you guys are useless HERE'S AN ACTUAL ANSWER.
I've heard that very fine steel wool will take the "KING" silkscreening right off of the aluminum, someone I know did that with a pair of cranks.
I recommended this in another thread and someone had this advice:
A dremel with a polishing pad and a little Mother's Mag & Aluminum Polish also works very well for freeing screen printing from aluminum. I've removed the 'Tektro' name off two sets of brake levers that way in seconds.
