Cast Iron
1) Properly seasoned cast iron, preheated hot enough is totally non-stick. Just as good as PTFE.
2) Gentle washing with minimal soap and no scrubbing won't harm things. I can't imagine why one would, but it's OK.
3) Works great on smooth top ceramic.
4) Is the very best material for induction and the one manufacturers calibrate to.
