Weird yellow stain any ideas?

Haven't washed my car for few weeks, got it washed twice within a week. There's this yellow staining all around my car looks like it's dried on, no washing will remove it, after clay bar still there it's not sap, haven't parked under trees, used iron x removers no luck? Anything I can do to clean it without scratching the paint

A good hand polish with a coarse pad or a machine polish would likely remove it but like mentioned above, hard to say without pictures
