I hate to dampen anyone's spirits, but blasting liquid or gaseous
carbon dioxide (dry ice) at something seems a really poor way,
environmentally speaking, to clean something (why not use compressed
air).  And I would certainly like to know what commercial companies
do this, so I might remind them of my concerns with global
warming.
