WELL IVE HAD MY WING OUT UNDER THE PORCH COVERED UP FOR A FEW MONTHS WITH ONLY THE TOP SKINS RIVETED ON. NEEDLESS TO SAY THERE IS STILL PLENTY OF DUST IN THERE. DOES ANY ONE KNOW OF A GOOD NON COROSIVE CLEANER THAT I CAN USE TO WIPE AWAY ALL THE DUST, PRIOR TO INSPECTION AND CLOSE UP. SIMPLE GREEN, AV8???. THANKS
