Things found in etching creams: Barium Sulfate, Sulfuric Acid, Sodium Bifluoride, and Ammonium hydrogen difluoride.
Hydrofluoric acid is the main ingredient that will etch glass. Overall, the cream is a diluted form of hydrofluoric acid. It's not nearly as dangerous as pure hydrofluoric acid but still, be very cautious when using it.
Glass etching pastes or cremes contain fluoride. The most common are sodium fluoride and hydrogen fluoride. This does not 'etch' the glass, it causes fluoridation which looks like etching.
One can order etching glass online on the official Martha Stewart, Hobby Lobby, and Michaels website. One can also order etching glass from either Amazon or eBay.

HF, Hydrofluoric acid.
If it has etched the glass,there is no way to remove it.
Everything from glass etching to tomato processing.
HF or Hydroflouric Acid
Look for the etching on the glass. If it says insulshield it has lo-e. If there is no etching look for a serial number usually between the glass then call Pella and give them that number and type of window they should be able to tell you what the build list was on that window.
fluorine is one of the things that they use to etch glass.
