This is very close to the old Neidner formula.
Used correctly, you can get different "colorings" depending on the steel.

I refinished (again) my 1911 this way and it turned out exactly like I wanted.

CAUTION: Mixing these chemicals is dangerous.

AAA... Alway Add Acid to water.

When The iron (I used baling wire) is added to the acids it produces a very toxic gas. Do this outside with some breathing protection.
