Before using anything aggressive that will harm the finish, I would give this product a try:
Top Gun Ultra Finish: Spruce P/N 09-00192
Google Aircraft Spruce and search the PN.
It will remove the oxidation from aircraft paint jobs (usually urethane paint) without harming the finish. It can also be used on the plexiglass windows and to polish the aluminum prop spinner. I use it on all my vehicles with great success.
They used to advertise that it was used on Air Force One...at least during the Bush administration. So if it doesn't work, there's one more blame on him.
Removing tongue from cheek...
