Do ammonium fluoride solution (2%) in water itch glass.

Yes, such a solution etches glass, but it does so quite slowly. It is comparable to the etching properties of a sodium fluoride or potassium fluoride
solution.
A better etching solution would be ammonium bifluoride, NH4HF2, which is more acidic and has stronger etching properties, while still
being less dangerous than solutions of HF. But also NH4HF2 must be treated with great care, especially its solutions in water. Neverl allow such
solutions to get in contact with your skin!!

It will etch you too if you're careless.
