Getting ferric chloride from Radio Shack is getting problematic. Is
there a common household chemical that I can use for etching a circuit

to do it in the not to distant past, but I can't find anything about it
in my back copies of Kitplanes.

You're thinking of this post:

Scroll down for Jim's response to RS Hoover's intial post. Muratic
acid and Hydrogen Peroxide.


Ah, yes! That's it.

Thank you...and Jim...and Mr. Hoover.

Ferric chloride is good, and I figured it could be had; but, it would be
a hazardous, special purpose chemical that would sit around for a very
long time with very little likelihood of ever being used again. Muriatic
acid and hydrogen peroxide are both useful for all sorts of things.
