That's a double edged ? For the WSCG, I think a little carbon doesn't hurt. Keeps rust at bay since it's steel. The WSCG comes with SS food grates though. I have a new all out aluminum PK as well. I don't know if I will let the creosote build up on this. I might keep the PK ~clean~. Then again, ALL the grills on my PK are SS.

For clarity, when say cleaning, just talking about the inside lid
