how to clean brushed aluminum faceplate?

I use Goo Gone. Probably the long lost brother of Goo Off. Got it at Loews.
Works like magic.

GOJO is my FIRST choice for almost all types of goo removal. Don't use the variety with pumice. It will definitely be abrasive.

Good luck

What Raquel said. (works for most any post too...lololool)

lighter fluid gets off goo

Goo Gone and Goof Off are definitely not interchangeable. Goo Gone is a citrus based cleaner, and Goof Off contains ethanol and Xylene (it smells like lighter fluid), so it *can* damage some finishes, although it takes off adhesives extremely well.

If your faceplate has a coating of some sort to protect the metal, Goof Off might harm it.

Raquel has a good suggestion to contact the manufacturer.
