Been flushing it out with clean water, but decided to use some Blue Devil coolant flush.. this is what came out!

will be repeating until it is clear.

it looks as though "Blue Devi" contains an active ingredient that dissolves grease and oil. i suspect that was what's (primarily) been removed from your coolant system. it would have some, but minor, effect on loose rust however. a mild rust remover may give even more dramatic results, i would imagine.

something like "Evapo-Rust" could be helpful, although i have never used it.
