Most traditional methods of cleaning require the aggressive use of abrasive cleaners and tools such as wire brushes and media blasting units. In today's world, people are looking for environmentally friendly and non-aggressive cleaning methods.
What Is Dry Ice?
Dry ice is frozen carbon dioxide, a normal part of the Earth's atmosphere. It is the gas that is exhaled by mammals and absorbed by plants and trees. It is also the same gas commonly used when making soft drinks and soda waters.
Dry Ice Pellets
Dry ice in the past has been used for many purposes, primarily freezing and keeping things frozen due to its extreme temperature. Dry ice is simple to handle with the use of insulated gloves.
Dry Ice Blasting
Dry ice blasting is similar to sand or soda blasting -- a granular substances such as sand, soda or dry ice explodes outward in a pressurized air stream to impact a surface to be cleaned. Here’s where the similarities end. Instead of using sand or other abrasive media to clean the surface, dry ice blasting uses soft dry ice that sublimates (turns into a gaseous state) on impact. The dry ice pellets create mini explosions that lift the unwanted material from the underlying substrate.
Before and After Dry Ice
Dry ice blasting is quickly establishing itself as the favoured method of mould remediation. It is superior to cleaning mould compared to traditional remediation techniques because it removes the microscopic layer below the surface on which the mould is growing, so the abrasion can scour off spores and discolouration left behind. By eliminating that layer beneath, dry ice blasting eliminates up to 99.999% of the mould spore and other organic contaminants from the surface.
Moreover, because dry ice sublimates on impact, there is no cleaning media to remove, as there is with sand. Only the material that was removed must be cleaned up.
