Before & After motor CO2 cleaning of rust, dirt and mold.
CO2 Paint stripping | On-site Industrial Cleaning
Dry ice cleaning is a process in which particles of solid carbon dioxide (dry ice), are propelled at high velocity to clean a surface. Upon impacting the surface, the CO2 particles return to their natural state as carbon dioxide gas, thus disappearing as they clean.
Although it is often compared to bead blasting, sand blasting, or soda blasting, dry ice cleans differently. Traditional abrasive blasting methods clean by abrading the substrate or removing a portion of the surface being cleaned. Dry ice, on the other hand, cleans by breaking through contamination and lifting it off while usually leaving the surface unaffected.
The dry ice particles break through the contamination but sublimate instantly upon striking the substrate beneath. This sublimation creates a compression tension wave between the contaminant and the substrate with enough energy to overcome the bonding strength and literally pop them off from the inside out.
When removing a wet or viscous coating such as oil wax, or grease the cleaning action is more of a flushing process similar to high pressure water. When the dry ice particles hit, they compress and mushroom out, creating a high velocity wave that flushes the surface clean leaving no residue behind.
