I don't think so. Gave it the same annual cleaning. The Coal Guns don't actually accumulate much ash over the course of a year. Also, my burn rate for Blaschak this season seems like it will be the mirror image of my burn rate for Blaschak 2 seasons ago.
Perhaps this is because I'm burning the exact same Blaschak as for 2 seasons ago. I do still have a different batch of Blaschak in the bin, but I'm working down my last super-sack of Blaschak first (so I can finally free up the garage for my car). Last season, despite still having the old Blaschak around, I switched to UAE Harmony as soon as it went int the bin, and I stayed with it until it was gone because it was amazing.
