Polishing Campagnolo Super
so here is my question . A seller on ebay is selling a fully polished set of Cobalto brake calipers . I dont want to buy them I want to figure out how he removed the anodized finish so well.
I have not got a reply from the seller so does anyone know how you remove anodizing without sanding it off
to me this was clearly stripped of without pitting the aluminum ....any help would be appreciated

Dedhed +1, 100% lye for ingredients on the cleaner helps, be very careful it is very nasty stuff. Don't get it on you skin or breath the fumes, watch it carefully as it will etch the Al after the anodizing is off. Likely will form a black smut which you can get off pretty easy. Light sanding may be required.

Once the anodizing has been removed, you'll need to polish regularly to keep the shiny appearance.

Those are highly desirable brakes -- did the guy just crucify the value of them by doing this? I imagine they still retain some value - i guess its debatable whether a fresh looking polished set would be more desirable than a scratched up , patina'ed set.

I took an old set of XTR cranks for my single speed to a local chrome shop. They had the polishing wheels and compounds to take off the anodizing and create a mirror finish.

Are you sure he took off the anodizing at all? To me the photo looks overexposed and the overly bright lighting is making the silver part look not that great. There is a real lack of contrast in that photo. The silver color of the part does not appear mirror smooth either. It almost looks like orange peel to me like you would see on an average silver anodized pair of sidepulls. If I were to guess I'd say the seller just had a clean used pair of Cobalto sidepulls and he cleaned them up real good with some car wax.

Works great on metals. Not sure what is in it but used it on my pots and pans for years.
