Nic, you are right, pickle shouldn't be diluted and poured down the drain. The website is being updated. It should be neutralised with an alkaline (eg soda ash) and evaporated. The liquid can then be siphoned off and the remains put in with normal rubbish. The Pickling powder does not contain copper.
what exactly IS safety pickle anyway? i mean i know what it is i just don't know what its mum calls it when its in trouble, the somethingium whatnotrate name.
Ok now I am confused again.
"Evaporate" - how? The only thing that comes to mind is boiling it dry?
"It should be neutralised with an alkaline (eg soda ash) and evaporated. The liquid can then be siphoned off and the remains put in with normal rubbish." - if you've evaporated it (the way I've said above?) then you don't have any liquid. Where exactly does the copper go if the remains can go in with the normal rubbish. Where do you dispose of the crystals Nic?
I give them to the council man labelled as Acid
