Soap and water, then white vinegar..... give it a try.How do you remove stubborn bird droppings from your car's paint after they have left a definite mark?
the mark would be etching from the acid in the bird droppings. clay is for removal of contaminates so this will do nothing to help the etching as the clear coat comprimised from the acid and actually eaten into the clear coat. you only option to get rid of it is polish. and not a cleaner wax but a polish with diminishing abrasives so it doesn't leave a haze that has to be polished out as well. i would look around the net and find a decently priced non over the counter polish(turtle wax etc.). and remember you get what you pay for. also an elctric orbital buffer would help tremendously.
You might try a clay bar treatment. (Mothers)
best stuff i found was turtle wax rubbing compound that stuff works miracles.just take a clean towel and apply it to the spot then rub rub rub.till its gone.
cut polish
