Leon thanks, ok right then, what do use as a hardware store, I have
sainsburys homebase and b&q, but I can guess before I take a trip
their if I write HCI on a scrap of paper, hand it to customer services
and say where do you keep this, I will get a very blank stare.........
Just what do you buy it as?
HCL is Hydrochloric Acid isn't it? In which case it is used as concrete cleaner and available in the building section of B & Q.
