Every time I try to wash the dead bugs off my black car with eagle car wash soap it does not work so good. I have used couple of times dish soap and works great but I know its not good for car finish, is there anything that works good with out hurting the surface of the paint.

 

Use a clay bar to get off old bugs..

 

After you clean them off apply some Zaino and they won't stick bad enough to need a claybar
