Default Re: Polishing aluminium

Soap filled steel wool, e.g. Brillo pads, are generally very good for producing a fine finish on aluminium but David's warning is very relevant.

The probelm with fan blades, assuming the material is basically sound is that any serious abrasion may possibly affect the balance. Scotch Brite pads are available in a variety of grades and will not remove as much metal, if any, as emery based abrasives. Again if the material can stand it, gentle bead blasting would be effective and could be followed by the steel wool.
