    That's an interesting article at the ganoksin site. However, I think
    that there might be a mistake in the text. 

    A formula reads: 

>    20% concentrated nitric acid
>    20% hydrochloric acid
>    20% lactic acid
>    40% distilled water

    and the mixing instructions read: 

>     Only a plastic container may be used, and care should be taken that
>     the environment is not too warm because hydrofluoric acid
>     evaporates at 16C (60F, rroom temperature). 

    I know that you can't use glass with hydrofluoric acid so
    "hydrofluoric" is probably the correct one rather than
    "hydrochloric". I'm sure it's just a typo but probably should be
    changed.
