Stole the method from this thread, red devil or drano crystals

1/3 cup of drano crystals per gallon of water. An oil drain pan from Walmart with the top cut off fits a 20" 406 rim perfectly. I filled a gallon jug with water to displace liquid in the tub so I didn't have to use as much chemical.
I've used oven cleaner before, its touchy and has always etched and spotted my parts requiring more sanding. It has some additional chemicals. This removed the anodizing well without the "side effects" and worked better.
I used 360 in a 1/4 sheet electric sander on the edges, then 500, 600, some by hand. Finer grit would have helped.
Polished with 2 compounds on buffing wheel. The compound was burning in worse than I've ever had, so I switched to dupont 7 rubbing compound for paint and buffed wet. Made a heck of a mess but it cut and polished.
Then strapped a piece of denim to the 1/4 sheet sander and used mothers.
Washed and wiped everything down, piled on turtle wax ice. I thought this stuff was gimmicky at first but tried it on some plastic trim, then on my daily driver. It lasts longer. Nice cars still get carnuba.
Gobbed on the ICE, heated the oven to 175, put the rims in the oven, turned the oven off, let them get up to temp then cool enough to be handled.
Gobbed on more ICE and polished it in.
My thinking was heating them up would open the porous surface and baking the wax on would get the best seal. Not sure if it will last any longer, but unlaced is the time to do it.
When youre done with the drano, it's a base, so neutralize with mild acid (vinegar) or just dump it down the drain.
Lye you say? Maybe a tutorial for this would be cool, I know I'd follow it!
