You do realise 'Cona' is a very, very rude word in Portuguese. I wonder if the makers of said coffee machines were aware it's not a name that travels well.

Commercially etched glass is done with hydrofluoric acid which is very nasty stuff if you get into direct contact with it - it's also a product of some burnt rubber objects, so use gloves if you happen to be stripping out a burnt car engine bay.

It doesn't appear to burn in the usual manner as acids do or can be washed off or neutralised easily should it get onto exposed skin, but it will damage muscle tissue by destroying the myoglobin so muscles will be starved of oxygen judging from a video I've seen that compared the usual suspects (hydrochloric, sulphuric and nitric acids) and also hydrofluoric acid and its effects on red meat.

It can't be contained in glass bottles or vats like other acids due to the fact it will destroy glass, so it's stored in plastic bottles and vats. From what little I know of its long term effects (a popular car repair manual states one cure is amputation of the affected limb), but looking further into it I've seen that patients contaminated with it are given treatment of a high concentrated calcium intravenous infusion to (I hope) remove it from their system.
