This is Fred Ball for Zions Bank, speaking on business.

Solid carbon dioxide — commonly known as dry ice — keeps beverages cool and creates fog for special effects. But did you know that it can also be an effective cleaning tool?

I was impressed to learn of the many applications for cleaning with dry ice when I spoke with Randell Heath, president of Coldsweep in Mountain Green.

Randell first used dry ice to solve his cleaning problems when he worked as a manufacturing engineer for Hercules Aerospace Company. Using a dry ice blaster, he eliminated the use of paint strippers, solvents and other chemicals used to clean rocket tooling. Dry ice blasting cut cleaning costs in half and prevented damage to the delicate aluminum tooling used to manufacture rocket motors.

In 2001, Randell left Hercules to form a company that offered cleaning services using this method. This month, Coldsweep is celebrating its five-year anniversary. Today the company provides cleaning services to the energy, food processing, printing and restoration industries, cleaning everything from gas turbines to pioneer-era log cabins.

Randell explained that his employees use dry ice blasters to propel dry ice particles at a high velocity. As the dry ice strikes a surface, it expands into its gaseous form and creates a shock wave that removes the contaminant from the inside out. Randell tells me this is an EPA, USDA and FDA-approved cleaning method that is non-abrasive to materials that are harder than dry ice. It is environmentally safe and produces no secondary waste.

Coldsweep has many different machines, ranging from high-power equipment to delicate machines that emit sugar-size granules of dry ice to gently clean sensitive surfaces. The company recently cleaned smoke-damaged books at the Sevier County Courthouse, some dating back to the 1800s. Earlier this year, Coldsweep removed lead-based paint from the decorative railing and stairs at the Utah State Capitol as part of the restoration project.

For Zions Bank, I'm Fred Ball. I'm speaking on business.
