[Rockhounds] attacking quartz without hydrofluoric acid

[Rik Dillen]

Ammonium hydrogen fluoride (NH4)HF2 or sodium hydrogen fluoride are somewhat milder, but even those are extremely
harmful substances that provoke bad burning wounds and if a drop touches the eye it can be lost in seconds !
All these products should be used only by trained professional chemists !

I was wondering if anyone knew of any ways
to get rid of quartz (such as in encrustations) 
without use of hydrofluoric acid.
