Gotta be careful with some chemicals on painted surfaces. Some will eat the paint as fast as the goop. And then there are the plastics.
I've used Gunk with pretty good results. It's intended for greasy engine areas (which of course are painted).
Another trick I've found that works as well as most others is that scrubbing bubble bathroom cleaner. It even takes splattered bug guts off grills and headlights better than most other specialty products.
I think the NON chlorinated brake fluids cleaners are LESS likely to bother plastic, but still might.
His Gunk idea will work well also.
Ok I just got to ask, how fast are you driving your tractor to get bug guts splattered on the grills and headlights ?
