Cleaning anodized aluminum porthole frames
Anyone got a good way of cleaning anodized aluminum porthole frames to bring back the new look? Or has anyone de-anodized them back to shiny aluminum, if so how did it come out looking?

Obviously you will have to remove the frames to do the job properly. Sodium hydroxide will remove anodization. Just for general information, most oven cleaners are simply jelled sodium hydroxide dispensed as a foam from the can, thus the dire warnings written on the cans. Remove the coating and have the frames clear anodized, paint them or if you want really shiny frames have them plated. You'll be polishing porthole frames for the rest of your life if you don't recoat them.

You may want to check with the anodizer before battling with any broken hardware. The anodizing process will remove ferrous items for you.
