How do you remove parkerizing?

[Questor]

How can I remove parkerizing right down to the bare metal? Thanks.

#1). Obviously, mecnhanically. Sand it off. Buff it off. Grind it off.

#2). As I recall the Am Rifleman article, this was a "porous" finish calculated to hold oils in the pores to prevent oxygen/water contact that causes rust. I think that many "blue removers" will tackle it, but I would ask Brownells [brownells.com] about their products. If you have to be crude, "muretic acid" is available at the hardware store (hydrochloric acid) should do it, but hard to control. luck

Parkerizing uses Phosphoric acid which etches the surface of the metal, and deposits a crystline layer on top of the steel.  I'd GUESS that sandblasting (carefully) to a matte finish would be your best option.  If you want a polished finish, I suspect there's a LOT of work involved.

Blast it with silicon carbide. Do NOT use aluminum oxide or you'll never get it to re-parkerize.
