Without question the best stuff I've found for cleaning airplanes is
Tomar TR-1000. It is designed to be safe for aluminum airplanes,
unlike the cleaning products you'll find in your local discount store.
It is extremely effective when diluted and used as directed.

Got an URL for these folks?

All I find in a search are dead and foreign language links.
