Cleaning abrasive compounds out of action

[Why not?]

........ Brake cleaner can remove bluing.

I have used it a number of times on blued steel, and never had a problem. How long does it have to stay on the blue?

Now, vinegar, blood, and urine; they will remove bluing in a hurry.

I think it depends on the level and quality of bluing.
