After proper removal of aluminum blade damage, the affected surface should be polished with

fine steel wool or scotch-brite.
very fine sandpaper or a crocus cloth.
soapstone or a wire brush.
a high polish machine finish.

The correct answer is: very fine sandpaper or a crocus cloth.

After properly removing the aluminum blade damage, using fine steel wool or a scotch-brite could potentially cause further damage to the surface. Soapstone and a wire brush are not suitable for polishing and are more commonly used for marking or removing debris. A high polish machine finish may be too harsh for the surface and could also result in damage. Very fine sandpaper or a crocus cloth are both gentle enough to not cause any additional damage while also effectively polishing the affected surface.
