After reading a reply in another thread from Mike from England Stoves, it reminded me of an item I wanted to post. Before burning this season, I sprayed the complete inside of my stove with a spray graphite as an experiment. I'm really pleased with the results. Less ash sticking inside and much, much easier to clean. I've used this product for over 20 years at work and always on my combustion blower, I'm surprised I never thought of it before.
