Where I used to work we cleaned up Detroit Diesel Crankshaft bearing areas with Emery Paper and lastly with 500 or 600 Corocas Cloth (not sure or the real spelling or real name).

The Corocas Cloth does not have a raised grit like even 1200 emery paper does.

Before any polishing is done it needs to be measured to see if it is out of round. If it is out of round beyond spec you need to find another Crank or have the original machined undersized.
