I have read that Manganese phosphate can be removed with citric acid without damaging the steel..  Anyone know any other way?

Greetings My Good TL

I always used a brass-wire wheel and a very light hand....

industrial folks use chromic acid ( aaaah!!!! )

the chemists say to use phosphoric acid ( like in coke) ...
For What It Is Worth,  I use the cheapest Cola I can find to gently etch damascus blades to bring out the pattern.

the hobbyists say vinegar, citric acid, soda pop, or naval jelly.
Or abrade it off.

They all say the finish ends up looking pitted or etched or sandblasted

This outfit claims they have a miracle drug cure !

"IOSSO QUICKSTRIP is a revolutionary product designed to remove Parkerizing and blueing within minutes without etching. Just immerse parts into Quickstrip solution and let soak for several minutes. Watch closely until completely stripped, then remove, and rinse thoroughly with water. Eliminates the need for bead blasting. Solution is re-useable. Quickstrip does not contain a rust inhibitor. Easy to use ? little odor! Environmentally friendly. "

Jeeeze! It sounds like one of my Snake Oil Speeches!

Wow, Midway has it:
