ok..not very technical but someone must know how to get them clean..without stripping the surrounding paintwork in the process! I really shouldn't have looked closely but the bonnet has a grimey dull look and the wing tops are shiny and now it's bugging me..pah! So..what takes it off...BTW fairy liquid may claim to cut through grease and grime but it bloomin well doesn't!!! I even tried the industrial car washing stuff neat....no joy...
all bright ideas here please!!!
