Cleaning inside of stove

im going to be cleaning out the inside of my Jotul Rockland. I have this crusty glaze buildup on where I believe the secondary air channels are as seen in pic. The stove is steel inside as opposed to cast face. Can I just use a steel brush to get this off or is a different method better? Late in season I have played around with lower air settings so this isn’t too normal for me. Thanks

Maybe run a short, hot fire to try and burn it off.

Good call, tonight might be it with temps in the low 50s as a high today. Might be my last shot, without cooking myself out that is. Thanks
