Don’t forget to clean the ashes out of the stove, too. Check your door gasket. The basic rule of thumb is that if you can close a dollar bill in the door and then pull it out with the door latched, it’s time to replace the gasket. Many serious wood burners also keep a pot of water on the stove to help keep the humidity in check. Often the water spills on the stovetop causing rust. Spring is the perfect time of year to touch up the stove and pipe with high-temperature stove paint.
Check your masonry work as well. Are there loose bricks, missing mortar, or other apparent damage? Now is the time to repair, waterproof, and rebuild any defective areas.
