It is known that this acid will burn through skin causing extensive damage and will continue indefinitely seaking for Calcium that will only be found when the acid reaches the bones. Eye contact even in tiny amount will cause vision loss. You should advice your audience to use extreeme caution in handling it and that no personal protective equipment is to much to handle this material, rubber gloves, rubber apron, face shield, rubber boots, filter mask, etc. Powdered lime should be at hand at all times. Please prevent anyone from getting hurt. HF is an extreemly dangerous acid.

NOW I AM A GLASS DESIGNER.ACID ETCHING & ACID FROSTING I PROBLEM FOR ICE CRYASTAL ACID ETCHING WORK. I KNOW THE ICE CRYASTAL ACID WORK PROSSES.BUT I DONOT KNOW THE ACID NAME. PLEASE SAY THE ACID NAME. PLEASE SEND ME YOUR MAIL IS ALWAYS ENGLISH. BECAUSE I AM A INDIAN I DONT KNOW CHINASE LANGUAGE. I MR NABIN MAJHI.

The glass is being de-faced with graffiti using Hydrofluoric acid. Is there any other chemical or process that would re-polish the glass to be clear again to hide the frosted appearance the HF leaves on the glass???

It also should not be posted without appropriate safety warnings. No one should get the idea, for example, that any of this would make a good science fair project.

HF can be fatal if inhaled or if relatively small amounts of skin are exposed to the acid.

See for example:
