Rodent Damage

::The chassis in your Hallicrafters is metal. ( Aluminum does not rust ) Mouse pee is ammonia that will etch and rust the chassis. Try Navel Jelly with a Q-tip. Let set awhile then wipe off. This should take way rust. The spotting will still be there though. Not much you can do about that.

:True, aluminum does not rust, but in my airline days, I removed many an antenna and tied back the co-ax under the baggage bins so sheet metal could reskin the bottom of the airplane from Fluffy and Fido being carried on planes and following their needs on top of the belly. Alumium will not rust, but urine will corrode it from here to who laid the rails. That is also why mercury isn't shipped on airliners. We used a liquid called "Alodine" that gave a layer of controlled corrosion, like bluing a gun, but eventually the airplane got a new bottom when the corrosion made it unsafe to hold cabin pressure. Small patches can be polished out and Alodined to delay the reskinning for a while. Aluminum polishes easily. Use car buffing compound.

Thank you for the replies! Lewis funny you mentioned car buffing compound as that is what I used to get me this far and it worked very well compared to the before


I used Turtle Wax rubbing compound and a couple medium toothbrushes with the heads bent. Maybe I should keep going with that. A disability limits my right arm and I am right handed so it'll be a process but do you think I can try a rougher grain compond and do it in stages? Although I think Warren is right about the etching it's pretty stubborn.
