interesting question, I would try and clean glass with it, If it cleans glass without leaving a residue behind I would use it. If you have a residue left over would not.
I would not. It is mostly anti freeze (propylene glycol) and
dipropylene glycol dimethyl ether which can be nasty off gassing. It is also a fire hazard, closely related to engine starters. I am not sure I would what either around a fdm 3d printer myself.
I tried it on a piece of glass and it left a very greasy residue on the surface. Had to wash it multiple times with soap and water and some isopropyl alcohol to get the stuff completely off. Really glad I didn’t try this on my build plate.
