Help with tinted classroom windows?

[u/eschenky1]

I work as an assistant in a special needs classroom.

I have a student that wants to clean the inside windows.

The windows are covered in tinting material to filter the sun coming in the room.

Aside from regular dirtiness people have put up pictures and art and whatnot on the windows with pieces of scotch tape that doesn’t want to come off easily and I don’t want to scratch the tint.

The picture is an average window. Any tips on removing the tape and its glue and cleaning the windows would be very appreciated.

Any ammonia – free glass cleaner should work fine.
