Somewhere on teh intarwebs someone wrote:
My local chemist who I have known for years won't sell me oxalic acid
(which I want to use for bleaching old linen and cotton fabrics)
because it's no longer permitted. It used to be, in the days when we
were treated as adults.

My local council give 2 litre containers of the stuff away to anyone who
asks as they have problems with rusty water sometimes. You just have to sign
a book and supply your address (to prove you're on town supply water).

Mind you, I live in New Zealand....
