Default how do you take the colour off anodised alloy

how do you do this? besides very fine wet and dry sandpaper, how can i take the anodised colour of a alloy chassis. 7075 aluminium? i don't want to scratch it whilst attempting to take it of.

i heard oven cleaners work? which ones though? i doubt most of the new age earth friendly c$%#p wouldn't work though? it isn't toxic enough

any other methods? has anyone tried using those creams that make alloy rims into chrome rims? does it work?

reason being i will be getting a chassis which is blue and i want it to be the natural alloy colour. alloy colour wasn't available.

Get some "EasyOff" oven cleaner. Spray it on wipe off what you can and then get some auluminum polish and go to town!
[You can also use other oven cleaners.]

Take it to a engine rebuild shop or machine shop and have it glass beaded, or bead blasted, then polish it.

2 teaspoons of Lye (Red Devil drain opener) in 1 liter (~quart) of water will take it of in 10 minutes

But you know that blank aluminium will corrode pretty quickly and gets black if you don't polish it constantly

Just be sure to wear rubber gloves if you decide to use Easy Off. I didn't use any and in the middle of my "de-anodizing" project, I noticed bits of skin were just peeling off my index finger. It took almost 3 weeks before the half inch split in my finger healed.

Also, if you leave the Easy Off on too long, it will leave a black "film"on the metal. You will have to go through the cleaning process again -- it will come off --, but it's very time consuming. It takes almost as long to get the black film off as it does the anodization.

Since you're doing a chassis, it shouldn't be too bad. I was doing cone washers and they were a pain because they were so small. With a chassis, the surface is nice and flat. I would recommend sectioning off the chassis and doing one part at a time. That way the Easy Off won't sit any longer than it should which may reduce the chances that the black film will appear.

Good luck,
