I've seen nurdRage. He does have good videos and this is no different.

Interesting about HCl + H2O2 (yes it does "decay").

And CuCl2 + HCl (stable). He says it can be regenerated but first line says that Chlorine is being used to create CuCl4 and use up HCl. I don't see how you can replenish Chlorine without adding more HCl.
Well he said he will have another video just on CuCL2 + HCl etchant.

He does have video on FeCl3 and tells you how to make it. Only thing I don't like is that FeCl3 stains everything. I guess the disposal of it is much easier. And I may go back to using FeCl3. Also easier to obtain or to make my own.

I can concentrate H2O2, so I can make it fairly quickly without diluting it too much.

Thanks!

Smiling Cat,

This has long been the definitive source of
info on CuCl around here.

You do need to top up with HCl every once
and a while. Only tiny amounts though.

I used to remove iron-based rust stains using a biodegradeable rust killer gel
that is discontinued. Another biodegradeable non-acidic rust killer should work
such as Evaporust (a chelating agent).

Ferric Chloride stains can be removed with Oxalic acid or commercial stain
remover.

Iron Ike removes a lot of "Fe" stains, although FeCl I haven't tried. Here's a link to the product:

I used it on a porcelain tub which had rust stains.
