Hello Jose,

I totally agree with the rubbing down with baking soda after the etch - this stops the continued etch and prevents eventual corrosion post etch.

Sure, with most acids a neutralization step is crucial. However, the main problem with ferric chloride is that it promotes corrosion even after full neutralization: any remaining chloride ions will act as catalyst for rusting. Forever! With many antique blades removing all chloride by rinsing/soaking is a real challenge if at all feasible!

BTW, the beauty of acetic acid (vinegar) is that any traces will evaporate upon gently heating the blade.

Regards,
Kai

Hi Kai. I have not had the problem. I guess by washing it off first, then rubber it with baking soda, then drying the blade off by rubbing, and then oil.
