Is this at Scrap I’m assuming it is

I dug a 318 crank out of the shed to see if it would clean up to use in my 273. It looked as bad as the one in the original post. I filled a 5 gallon bucket with white vinegar, and suspended the crank into the bucket with a ratchet strap until it was just off the bottom of the bucket. Took it out after one day, and cleaned it up with WD40 and a plastic bristle brush. It was perfectly clean. I flipped it over and soaked the other end in the vinegar, and cleaned it up. Neutralized the vinegar by pressure washing it and wiping it with baking soda. I sprayed it down with oil, and wrapped it up in plastic. I took it to my machinist, and it is already .010-.010, and he says it needs a light polish to get the clearances in the middle of the range. Vinegar is cheap at Sams Club or Wal Mart....and the sides of the interstates are littered with 5 gallon buckets, so.......
