Hi everyone. I am an engineering student. I read something called dry ice blasting while browsing net. Well I don’t know why, but I am curious to know about it. I know about traditional labor intensive methods like scrapers, wire brushes, sand blasting and pressure washing. I know dry ice is basically solid form of CO2, but I have no clue about this dry ice blasting.
Can somebody throw some light on this or at least suggest some site where I can find some info on this.

Well, it's like sand blasting, but much more effective. Dry ice pellets are used as the blasting medium. The pellets are accelerated to supersonic speeds, and blasted against the surface to be cleaned. Due to the sublimation process, the pellets create small explosions as they turn into a gas, cleaning the substrate underneath. There's a lot more detail here.
