Wendy,I used Wed crawler for the rearch engine and typed Dryice blasting,found several pages.Found one web page stating they did dryice blasting along with,flatwork,woodwork,ect..
Walt you can buy your own dryice maker,sames tho the CO2 would be a hassss'le.
It has its benefits,no harsh chemicals to reclaim or harm,no water to slip down in or shorting something out.I can see where it has a market for itself in our trade,I'm not looking for that type market to get into.
Some of the eqt. used different size ice as to its cleaning and can be shipped to ya.
