Major brake dust on rear of raw Aluminum rims?

[ETsC10]

I’ve been gifted a pair of rotary forged Centerlines that
I really love the look of but cleaning the buggers have
me afraid of damaging them or having to put too much
elbow-grease into the project (I have RA in both hands).
The backs are totally, thicky covered with road dirt and
brake dust.

What will safely remove this grunge chemically?
(especially on the back side)

It seems the fronts are polished but the backs are surely
raw...need something safe both for me and the wheels.

BTW---I’ve looked around a lot and still can’t ID this
Centerline model…seems to be a year-specific weirdo.
Any clues are welcome.

Thanks guys! E
