I am rehabing my water/wastewater bay. There are large, decorative metal panels that are brushed aluminum. To clean those up I have experimented using a metal polish (Noxon brand, a thick liquid) followed by Pledge as a sealant (I read about Pledge for brushed aluminum on another site). This method brightens up the brushed metal surface and the Pledge does not leave a wax residue that would be difficult to buff out of the brushed surface. I am wondering how long the Pledge will protect the surface. Maybe I should use something else. Alcoa has a sealant to use on their rims after polishing. Maybe that would be better. Anyone else have experience with this issue?
