Suggestions on cleaning intake manifold-inside & out

1995 Formula LT1 - bone stock, 138k miles
I'm halfway through the intake manifold oil leak fix. I have the intake off and the fuel rail and throttle body off it. Now, I have lots of cleaning to do.

I assume that the best way to clean the inside of the manifold and the TB is with carb cleaner. I also have 2 cans of brake cleaner that I would like to use up. Is there any problem using brake cleaner instead?

I'm also looking for any suggestions on cleaning the exterior of the manifold to brighten it up. Anything that's worked particularly well, or anything to stay away from?

Thank you!

Yeah, thanks.
Didn't realize it wasn't for LT1. I saw External Engine and Manifolds in the description, but missed that detail.

I don't think it would hurt anything, brake cleaner is supposed to evaporate completely. You could try some wire brushes for the gunked on ****, but make sure you don't leave any wires behind.
