I have taken my stove apart once this season to clean the cats. That was about a month ago. Since then, on more than one occasion I have noticed the cats looking a little dirty and clogged. on occasions where I have let the stove burn down to nearly nothing, I will open it up for a few minutes, and give the cats a blow with canned air. I'm carefull not to put the nozzle too close so as to avoid supercooling the substrate. that removes dust/ash but the hard stuff stays on there. When I get the stove up to hot, it seems to burn the krud off and they fire right back up. my left one is kind of bad right now. I'm not sure it's firing. I'm gonna have to let the stove die down pretty much at some pointand blow it out in hopes that that's all it needs. otherwise I'll have to do a dissasemble. much sooner than I had planed. The right one was glowing bright a little while ago.
