I've been using NIR chalk for a long time now, along with Blue Diamond depending on what I grab first out of my case. Well, I've switched back to Master chalk.
NIR and/or Blue Diamond managed to stain my ferrule (whatever is stock on an OB Classic Pro). I chalk properly, I wipe down my shaft almost every time I chalk, and I will run Q-Smooth papers over it once in a while. I stopped using the NIR and Blue Diamond after I noticed the first stain (pictured). Ever since then, it has actually faded. I've only been using master chalk, and I feel like I haven't miscued any more/less. That might be due to my stroke improving, but that's irrelevant. I'll keep it in my case as emergency chalk but that's it.
