I wouldn't want to clean a crank, rods or valve springs with anything but brake cleaner. Incidentally, any rust on valve springs and they should be tossed, as rust on a spring causes a defect that can cause it to break.
Just looked up the pH of Chrome Wheel cleaner on its SDS. It's "2-3" Pretty big spread, but somewhere between vinegar and apples.
