Racing engine parts manufacturers

Wet-sand them carefully using 320-grit emery cloth mounted on a flat orbital sander or sanding block. When you do this, make sure that you don't put a taper on the edges. Keep spraying them with water and put on more Comet as you sand them.

Rinse them off, dry them with a clean towel, and inspect them.

Spray more water and more Comet on them.

Wet-sand them with fine Scotch-Brite as above.

Rinse them off, dry them with a clean towel, and inspect them.
