What can dry ice clean and how does dry ice blast cleaning work

Whether you’re an insurance adjuster, business owner, contractor, builder, or homeowner, you’re probably facing a serious cleaning challenge and wondering why there’s no better way!

Well, now there is. Now there’s a better way to clean almost anything in any situation. What is this “better way”? Dry ice blasting! 

What is dry ice?

First, let’s discuss what these things actually are ……

Dry ice is not “ice” at all.

In fact, it’s actually just a freezing gas – carbon dioxide gas to be exact. So that means we can’t look at this strange substance like ice, mainly because it doesn’t melt – it “sublimes”.

Sublimation is the act of converting (relatively) hard frozen carbon dioxide “dry ice” particles back into gaseous vapor. Sublimation occurs when the frozen gas hits an object or surface with a mass greater than that of the pellet. As sublimation occurs, the pellet disappears completely into the gas.

To make dry ice, first, use a high-pressure container filled with liquid carbon dioxide. The liquid carbon dioxide is then carefully squeezed out of the tank, the liquid expands, and the high rate of carbon dioxide evaporation cools the liquid to its freezing point, where it turns directly into a solid. This solid can be made into blocks, pellets, or even snow-like material.

What can dry ice clean?

“So what will these magic particles clean,” you ask.

The ice cube cleaning process will easily, neatly, and efficiently clean contaminants such as

Grease, oil, and various petroleum products

Cutting oils, miscellaneous lubricants, gels, and pastes

Old, loose paint

Mold removal

Burnt wood, soot removal

Mildew removal

Dirt, grime and debris adhering to walls, ceilings, etc…

Rubber and injection mold scrap

Old plaster, mortar and debris adhering to brick, masonry and concrete

The list goes on ……

In most cases, dry ice can be used to clean most contaminants. And, because dry ice is non-conductive, this cleaning process is also suitable for electronic components and sensitive computing components.

How does dry ice blast cleaning work?

So we now understand how CO2 pellets are formed by extruding liquid CO2 under high pressure. The CO2 in pellet form is stored in an insulated container until it is ready to be used in a blast cleaning operation.

The pellets are first loaded into a hopper that combines the air pressure (usually provided by a commercial air compressor) with the pellets and directs this air/pellet mixture into the “gun”. In this case, the “gun” is simply a nozzle controlled by a trigger or switch that allows the operator to aim and control the flow of compressed air and CO2 pellets.

The pellet and compressed air mixture are propelled at speeds between 80 PSI and 350 PSI. The lower speeds are used for small, delicate cleaning processes, while the higher speeds are used for cleaning hard contaminants and heavily contaminated substrates.

Contaminants are “fast frozen” as the particles and compressed air impact the item to be cleaned. This rapid freezing process breaks the bond between the surface of the substrate and the contaminant we wish to remove. The air pressure then “blows” the contaminant away from the substrate, and the contaminant simply falls to the floor. The collective waste can then be safely cleaned up and disposed of in accordance with local laws and regulations.
