Same here. But after years (2 or 3) salt forms on the ouside of the
bottle.
also the plastic gets dimples. i put it in a cutoff "outer" bottle so i
needn't touch
the salts. Not a problem but it is very slightly attacked. The salts
seemed to form faster on the bottle i used to store the CuCl, which was a
PP bottle i think.
I wonder a lot about this hcl brick washing thing. I hear it so often i
must ask
google for a description.
