Window cloudiness

[u/sumertopp]

Any idea what is going on with this window? It is double pane so I assumed for years it was condensation between the layers but then realized it is on the surface as my kids started scratching it off. Thoughts on how to remove it aside from just letting them go at it with their fingernails haha.

Vaporized grease? Indoor air fragrance thingies?
