I've been following a long thread on this on the Pelican 911 board (I'm rebuilding a 3.0)......Popular opinion is that hot soapy water and scotchbrite pads are best for the Nickasils. Don't know about pistons, but I've used Brakleen spray on them....with a soft brass brush on the crowns to get the carbon off. There's probably a better way short of bead blasting (don't blast unless you mask off everything but the top).
