That was the dried on bird crap you left on your car actually if i remember! To be honest by the time you've left a wet cloth on there you might as well just wash the whole bloody car!
The most annoying thing is when you're car is otherwise clean and shiny but you can't get the dead bugs off without actually going through the whole bucket of hot soapy water procedure. None of the sprays i've ever used have been any good.
I knew that was going to totally FREAK me out but i still had to look! I am literally shaking at my desk and in need of a tranquilizer! I won't sleep tonight i'm sure!
