Industrial cleaning has historically involved a familiar set of trade-offs: chemical solvents that require containment and disposal, water-based methods that require drying time and create secondary waste, and abrasive blasting that removes surface material along with the contamination.
Dry ice blasting solves most of those problems at once, which is why it has moved steadily from specialty application to standard practice in manufacturing, food processing, automotive, and facilities maintenance over the past two decades.
This guide covers how the process works, which applications it fits best, the pellet size decisions that matter for equipment compatibility, and what operators need to think through on the supply side before adding it to their maintenance program.
How Dry Ice Blasting Works
Dry ice blasting accelerates pellets of solid CO2 through a pressurized nozzle at supersonic speed. The cleaning mechanism is three-part.
The pellets’ kinetic energy breaks the bond between the contaminant and the surface. Their extreme cold (-109°F) causes the contaminant layer to contract and crack, while immediate sublimation expands the pellets to roughly 800 times their original volume. This gas expansion penetrates beneath the contamination and lifts it away from the substrate.
The result: the surface is clean, dry, and free of secondary waste from the cleaning medium itself. The only material that needs to be collected and disposed of is whatever was removed from the surface.
Research published in the Journal of Cleaner Production evaluated dry ice blasting against conventional industrial cleaning methods and confirmed its effectiveness in removing industrial coatings, oils, and biological contamination while generating significantly less secondary waste than aqueous or solvent-based alternatives.
Where Dry Ice Blasting Works Best
Manufacturing and Production Equipment
Production equipment accumulates grease, oil, adhesives, and process residue over time. Traditional cleaning requires disassembly, solvent application, and drying before the line can return to service.
Dry ice blasting cleans most production equipment in place, without disassembly, and leaves equipment dry and ready to run immediately. For operations where downtime is measured in cost-per-hour, the ability to run cleaning cycles without extended shutdowns has a direct economic value that offsets the supply and equipment investment.
Food Processing Facilities
Food processing environments require cleaning methods that leave no chemical residue. Dry ice blasting is USDA-accepted for use in food processing facilities and cleans ovens, conveyors, mixers, and processing surfaces without introducing moisture or leaving secondary contamination. Equipment can return to service faster than with wet cleaning methods, and there is no wastewater to manage or chemical residue to verify.
Automotive and Aerospace
Paint prep, mold cleaning, adhesive removal, and engine bay cleaning are common automotive applications. Dry ice blasting removes contamination from complex geometries and tight spaces that manual cleaning methods struggle to reach consistently, without abrasion to the underlying surface.
Facilities Maintenance and Historical Restoration
Facilities maintenance applications include electrical panel cleaning, HVAC duct cleaning, and fire damage restoration, where soot, smoke residue, and contamination need to be removed without introducing additional moisture or chemicals into sensitive environments. Historical restoration uses dry ice blasting to clean stone, brick, and architectural surfaces where abrasive methods would remove material as well as contamination.
Pellet Size and Equipment Compatibility
Dry ice blasting equipment is designed around specific pellet formats, and the format choice affects cleaning performance, equipment wear, and supply logistics.
Standard Pellets (3mm)
Standard 3mm pellets are the most widely used format. They work with most commercially available blasting systems, balance kinetic impact and sublimation rate well across a broad range of surfaces, and are the default choice for most industrial applications where surface type varies across the cleaning project.
Micro Pellets (1.7mm)
Smaller diameter pellets are used for sensitive surfaces where standard pellets carry too much kinetic force, for intricate geometries with tight clearances, and for applications where a finer blast pattern is required. Electronics cleaning and precision tooling are common use cases.
Dry Ice Rice
Rice dry ice offers maximum surface contact and is often used in food processing and biotech applications where thorough coverage of irregular surfaces matters more than high kinetic impact. The smaller particle size also sublimates faster, so quantity planning for rice applications requires some adjustment from standard pellet calculations.
Equipment Compatibility Checklist
Before specifying dry ice for your maintenance program, confirm:
- Your blasting system’s recommended pellet size and the manufacturer’s tolerance for variation
- Air supply requirements, specifically CFM and PSI, and whether your compressor meets spec under sustained use
- Hose diameter and length for the equipment and the application areas you are covering
- Ventilation requirements for the space being cleaned, since dry ice blasting releases CO2 and confined spaces need airflow

Supply Planning for a Dry Ice Blasting Program
Dry ice sublimates continuously from production, which means supply planning for a blasting program requires more attention than sourcing a material with a stable shelf life.
A typical dry ice blasting system consumes between 300 and 700 pounds of pellets per hour depending on system pressure, nozzle size, and the application. A half-day cleaning project can move through several hundred pounds of pellets, and ordering too conservatively creates operational delays when a supplier cannot deliver same-day replacement stock.
Operators adding dry ice blasting to a recurring maintenance program benefit most from a supplier relationship with consistent inventory in the required format, delivery windows aligned with project scheduling, and volume pricing for regular orders.
AdChem supplies dry ice pellets and rice formats to industrial operations across California and Colorado from distribution hubs in the East Bay and Los Angeles. Same-day delivery is available throughout California for orders placed within the daily cutoff window. Contact the team to confirm format availability and build a delivery schedule around your maintenance program.
