I may be wrong but , I don't think aluminum turns black like that - but brass does . Can you see any screws that holds the cage on ? And the shaft to the blades ,that goes into the motor housing , may have a tiny set screw that holds the blade unit on .You have to get the cage off to get the blades off .Make sure you put bolt ease oil on any screws before working them- you should have the blade unit off in order to polish it properly - I use NOXON metal polish - works good .I took magnet to the blades....non-magnetic.....are they brass or other metal (aluminum ??)
The magnet stuck to the fan guard and fan base.
Thanks everyone for your previous input!!!
