Windshield Cleaning Help…

My window is covered in a film that makes the glass look bumpy and distorts light a great deal. I believe some type of wax or other hydrophobic liquid managed to get all over my windshield. I have tried a host of different products but none seem to make a dent. Images attached are hard to make it out but thought they could help someone point me in the right direction. I went over the whole thing with a razor blade and some water to try to take a top coat off but it’s all the same. Has anyone dealt with this have have a proven more aggressive solution than what’s listed above?
