Hi everyone. I am an engineering student. I read something called dry ice blasting while browsing net. Well I donâ€™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. Sam.
