Fire and Ice: A Soot Removal Technique Using Dry Ice Blasting.

The article reports on the significance of a soot removal technique using dry ice blasting. The preservation technique was developed after a fire caught the Sevier County Recorders Office in Richfield, Utah which left a powdery soot on the hundreds of full-leather spring-back stationer's bindings. Several traditional preparations and techniques have been developed to remove the soot's grey residue which include wiping of a chemical compound with a natural sponge, vacuuming with a high efficiency particle filter combined with manual wiping, and thermal oxidation deodorizing. However, dry ice blasting was given consideration in the problem facing the county because the system is portable, can be run by a generator, and cleans much faster then traditional cleaning methods.
