Thanks... I'll give that a shot... learn't the hard way that it scrathches paint when you try to clean it...
Bicardinate of soda also good idea! They are flying rats. They also tend to nest very near to where I have to park. Tempted to buy an air pistol and leave a couple of dead ones there as an example to rest of them!!
mix up some nice warm frothy shampoo (not herbal essence car stuff lol) and with a sponge squeeze some out on to the mess leave for a while then hose off, failin that do what Faz said any type of sponge will drag the sh!t across your car!!
if none of that work sand blast it off defo wont have any left after that!! lol
