Russel,
? Do you use your etchant around tools like in a shop environment? I know the HCI is the troublemaker but how does the polystyrene help? I have somewhat of a machine shop so lots of steel and tooling etc to worry about.
Thanks

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? 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?
I just put a slab of polystyrene over the container. If it's a bit warped, put a bit of wood on top of that.
I've had the same setup and *same* etchant in my lab over 5+ years, topped up with a bit of HCl every time i use it.
It's the HCl vapours that cause the corrosion.
