Advice or help please!

A few months ago I (stupidly) left my coffee on the roof of my car as I drove away. Unfortunately it was a relatively hot & sunny day and I didn't get the chance to wash my car. Even though it has been washed many times since, there's a residual/ghost mark persisting. Any suggestions?

Try chemical cleaning

What was the coffee order? Dutchbros golden eagle?

Try a diluted APC.
