Others may chime in since this is a somewhat controvercial topic. I believe Henry Schmidt at Supertek recommends that you lightly scuff them up with a scotchbrite pad in soap and water. That's what I did when re-ringing my Nickasils. Seems like the rings seated fine.
Others may say to just leave them alone. My exeperience is very limited, but it seems to have worked for me.
