In industrial and commercial settings, maintaining cleanliness and hygiene is essential for safety, productivity and compliance with regulations. Traditional cleaning methods often rely on chemicals that can be harmful to workers and the environment.

Dry ice blast cleaning offers an innovative, chemical-free alternative for cleaning in industrial and commercial environments. Its effectiveness, coupled with environmental and safety benefits, makes it an attractive alternative to traditional cleaning methods.

By understanding how dry ice blast cleaning works and its applications, industries can transform their cleaning processes, reduce environmental impact, and improve overall efficiency. Investing in this technology can lead to cleaner, safer workplaces and contribute to a sustainable future.

WHAT IS DRY ICE BLAST CLEANING?
Dry ice blast cleaning is a cleaning process that uses solid carbon dioxide (CO₂) 3mm dry-ice pellets as the cleaning medium. These dry-ice pellets are accelerated in a pressurised airstream from a dry-ice blaster and directed at the surface to be cleaned.

On impact, the dry ice sublimates, turning from a solid state directly into gas, leaving no residue or water behind. This method is highly effective for removing contaminants without damaging the underlying surface.

HOW DRY ICE BLAST CLEANING WORKS
The dry ice blast cleaning process involves three primary actions – kinetic energy, thermal shock and gas expansion. When the dry ice pellets strike the contaminated surface, the kinetic energy helps dislodge dirt and debris. Simultaneously, the thermal shock caused by the extreme cold (-78.5°C) of the dry ice causes the contaminant to contract and become brittle, making it easier to remove.

Finally, the gas expansion on sublimation creates micro-explosions that lift the contaminants off the surface.

APPLICATIONS OF DRY ICE BLAST CLEANING
Dry ice blast cleaning is versatile and can be used in a wide range of industries. In the automotive sector, it effectively removes grease, oil, weld spatter and carbon build-up from machinery and parts without the need for disassembly.

The food and beverage industry benefits from its ability to clean equipment without leaving chemical residues, ensuring product safety. Dry ice blast cleaning is also used in the printing and packaging, injection moulding, foundries, power generation and electrical industries, such as cleaning sensitive components and equipment in substations without causing damage.

BENEFITS OF DRY ICE BLAST CLEANING 
One of the primary benefits of utilising dry ice blast cleaning is its environmental friendliness. Since it uses no chemicals, there are no toxic fumes or secondary waste to dispose of, making it a sustainable cleaning option.

The process is also non-abrasive, meaning it won’t wear down or damage surfaces, extending the lifespan of equipment and machinery. Dry ice blast cleaning is highly efficient, reducing downtime and labour costs associated with traditional cleaning methods.

SAFETY CONSIDERATIONS
While dry ice blast cleaning is a safe and non-toxic cleaning method, there are still important safety considerations to keep in mind. Operators should wear appropriate personal protective equipment such as gloves, safety glasses and ear protection to guard against the high-pressure air, dry ice and debris removed from the surface.

Adequate ventilation is also necessary to prevent the build-up of CO₂ gas in confined spaces, as it can displace oxygen and pose a suffocation hazard.

IMPLEMENTING DRY ICE BLAST CLEANING IN YOUR FACILITY
Implementing dry ice blast cleaning in an industrial or commercial setting requires investing in the appropriate equipment and training for personnel. Dry ice blast cleaning machines vary in size and capability, so it’s important to select one that meets the specific needs of your operations.

Training allows operators to safely and effectively use the dry ice blaster, maximising the benefits of this cleaning method.
