Someone left pencil marks above the original hash marks on the
aluminum skirts on the tuning knobs on a Johnson Kilowatt Matchbox. I
have resisted the impulse to take eraser to the aluminum, as that might
smear and further embed the pencil lead.
Hints? Citrus-based cleaner? Isopropyl alchohol? Liquid dish-soap?
Thanks!
