Finally got around to cleaning the stoves this weekend. After 2 seasons with this Regency we are still very pleased. Nothing broken, bent or warped!! The glass cleaned right up -it was a little gray from the last of the spring fires. I still can figure out how to remove the air tubes though. They are in good condition but it would have been easier to brush down the stove walls with one or two of them out. The book just says to slide them to one side but they won't budge and I did not want to break what wasn't broke! Anybody have any experience getting these tubes out?
