I have not removed mine. My rollers were already melted either from other hot cooks or the previous owner melted them. I've since replaced mine with wooden roller from Brian and they have turned somewhat black where they meet the kettle. I would suggest removing your rollers, but you can leave the lid bale. Or just leave them on and if they melt you can replace them, I don't think they are very expensive. I'd also note that you can't put your lid in the bale with the KP on the kettle, there isn't enough room.
