After seeing some guys post on leaving his etchant tank out in his shop,
and the next day his drill press post was solid rust... I was thinking
that I really don't want to mess up my steel building or anything in it.
That said, if I use the muriatic/peroxide etchant outside, and then pour
it into a sealed container, I should be ok?
Define "sealed".....
In a one gallon glass or plastic bottle like the one the muriatic acid
is sold in.
Main problem with some enclosures is that the caps or seals are
attacked by the HCL. Rubbermaid cereal containers (inexpensive, but
while the bodies withstand the HCL, the seals don't).
Or if not if I really want
to be sure, what is the best of the other etchants that works the
fastest with no worry of rusting my stuff? Or am I being too paranoid?
Likely ammonium persulfate or ammonium perchloride. That still will
release extra oxygen here and there, but not acid fumes, afaik....
You could put it in a jug, say one used for distilled water or the
same one used for the acid (if you know someone who uses pool acid,
see if they have an old empty bottle.
I was tempted to (and almost did) get one of those brown resin
containers to put the acid in (suitably bottled).
No, you are not being too paranoid. I'd store it outside. I suspect
that the main problem is the fumes from the acid, but then again, no
idea of how well the container was sealed.
what would work should be a bottle designed for acid storage, say from
a chemical supply store.
Isn't a Hydrogen peroxide bottle a brown resin bottle like this one?
Yep, H2O2 tends to decompose in the presence of light/ultraviolet
light.
I'd wonder about the caps, though, for the HCL.
