Dry Ice Blasting was used in a Historical Home located in Vader, Washington for removal of soot staining from rafters located in the attic.  The loss was caused by a lightning strike via the lightning rod located on the roof.  

Dry Ice Blasting can be performed in a closed environment, eg. in a house or commercial building, since there is no secondary debris left behind. This application eliminates the need to use toxic chemicals to remove the soot from the fireplace brick.
