The Coulson IceStorm technology can be used to clean smoke damage off of wood. When cleaning wood, the ice breaker flare nozzle should be used. This is the gentlest nozzle available. Little pins, strategically spaced within the nozzle, break the ice into smaller particles and slow them down. These small, slower moving ice particles provide enough power to clean ash from the charred surface, but are gentle enough not to damage the wood beneath.
