hausdok Posted April 21, 2013 Report Share Posted April 21, 2013 When that gas burns off 70% of the exhaust is water and the rest is particles of sulfur and other junk. When you start up that stove cold the sudden burst of moisture inside the stove in the exhaust cools to dew point and condenses on the glass door. It takes a few minutes for the stove to warm up enough to evaporate that moisture. In the meantime, sulfur particles in the air cling to the moisture and remain after the water evaporates. Over time, the buildup clouds the glass and if it is ignored long enough the sulfur will eventually etch the glass. Part of the annual maintenance on that stove is to clean that glass.

kurt Posted April 21, 2013 Report Share Posted April 21, 2013 Yeah. Newer stoves have draft configurations that "wash" air across the glass to minimize the mess. Quote Link to comment Share on other sites More sharing options...

Brandon Whitmore Posted April 21, 2013 Report Share Posted April 21, 2013 A damp rag will wipe off a large percentage of that build up. Just let your customers know that they shouldn't be using ammonia based glass cleaners. Quote Link to comment Share on other sites More sharing options...
