Family: Hydrogen Fluoride
Formulation: Hydrogen Fluoride in water
Uses:
Concentrated solutions of HF will remove just about anything and everything from glass and will even etch the surface of the glass itself. It should not be used on calibrated volumetrics.
CAUTION!
All of these methods will do severe damage to the eyes, skin, mucous membranes and lungs. Extreme caution should be exercised when using these methods. Wear butyl gloves (not latex or nitrile exam gloves), eye protection and a lab coat. Work in the hood.
HF causes severe, painful burns that do not heal well, and prolonged or intense exposure can lead to a very slow, painful death.
