Cleaning the e-torque system?

[Theo2019]

So I was working on cleaning the engine bay and started wondering if I should be cleaning up the etorque box "the box"? Should I be hitting the box with some light WD40 or some other cleaner to keep it from rusting up? It looks a little rough the way it sits now. I'm not talking about spraying it down (especially not on the belt) but just hitting a cloth and wiping it down?

Pretty sure it's aluminum so it'll notbrust. If you want, take some steel wool to it or some brake clean .

it will get crusty if its aluminum but wont rust. dont use any acids under the hood when cleaning under the hood.
