I bought some of this at West Marine and have been using it to clean the airplane which is unpainted. It needs to be wiped off right away or it forms a thick film. If you goof, the film can be removed with another spay.
Seems to work well. I use it on all surfaces, except the plexiglass. I think I've done all the top & side surfaces and will start working on the bottom next. I'll let the list know how it works getting the black gunk off the bottom.
Seems to have all the properties I'm looking for:
