Cleaning steering rack

[ebox86]

So im putting my e36 m3 rack on soon and i want to clean it up a bit first.

I have gotten most of the oil/dirt residue off of the rack and cleaned it with mineral spirits but it seems its still dark and dirty, unlike some racks i have seen on here after cleaning.

Are these racks brass or some other metal that i should use a special cleaner for?

What are some products/chemicals that have worked well for cleaning these?

I use Spray Nine

Degreaser and a wire brush. If you can use a pressure washer use that if not boil some hot water and throw it on after you have decreased it and scrubbed it.

Wire brush and drill

I just spray a fuck ton of brake cleaner...

They are cast aluminum. My preferred de-greaser is Super Clean. Do you have a picture of the "darkness" you are talking about?

heres what it looks like, i've seen people clean these up on build threads before looking really nice, bright aluminum/metallic shine, but i think i need to try some harsher degreaser

Brake clearner and that 'Spray Nine' or 'Super clean' products all sounds like good ideas

Try zep industrial degreaser, just don't get it on your hands or stay in a small room with it cus its strong
