How to clean a surface using dry ice blasting

According to cleanblasting.com, there are three steps in the process of dry ice blasting.

Step 1 –

            The dry ice pellets are sent out of the blasting gun at a high speed creating a forceful impact when hitting the surface that they are projected at. This energy transfer causes the surface to be cleared of any extra dirt/contaminents without damaging the surface underneath.

Step 2 –

            The dry ice is a very low temperature of -79 degrees Celcius causing a micro-thermal shock when the dry ice pellets come in contact with the contaminents and surface that they’re hitting. This micro-thermal shock is what also cracks and removes the particles after the initial energy transfer.

Step 3 –

            The last step of the dry ice blasting process is the gas pressure. As the dry ice pellet explodes on impact, it converts to a harmless CO2 gas that is forced between the contanimenent and substrate layer forcing the last of the contaminent layer away from the substrate, leaving only the contaminents to be left behind and the substrate unharmed.
