I know this subject has been beat to death, but I'm trying to remove the anodizing from the aluminum mouldings on my 63 Galaxie with the over cleaner method so I can then polish it. It does not work at all. I'm using Walmart brand oven cleaner (which may be the problem). I checked and it does contain sodium hydroxide. I have experimented with the time and done everything from leaving it on for 5 minutes, to two days. Same result every time: anodizing is still there and just as intact. What am I doing wrong? Is there a particular brand that I should be using? When I research this, I see that half the people that have tried it say it worked perfectly, and the other half are like me and say it doesn't work.
