Cold blue solutions

I have one part to blue it currently has an antique finish on it. What would be the best way to remove the antique finish and blue the part. I was thinking on using Laurel Mountain Forge so what would be the best method for a durable blue finish?

It is usually not desirable to remove an antique finish.    However, if you intend to proceed with a blue finish.   I would do a rust blue using browning solution.   I believe that would be the most durable.

Is an antique finish tough to get off? I was thinking to use naval jelly to remove the antique finish then boil the lock plate in distilled water and apply the Laurel Mountain. No good??

First step, if you want it darker, put the old  lock plate in steam or boiling water to darken the rust. Then use fine steel wool to remove the loose rust after it dries.  Should be dark. Best course is to leave it alone and make the new part look like the old part.
