Conveniently located in Guelph, just outside of Toronto, Wickens Dry Ice Blasting provides Dry Ice Cleaning services and Dry Ice Blasting machines and equipment, to all of Ontario and across Canada. Dry Ice or CO2 Blasting is a cleaning process using solid CO2 pellets (known as dry ice). Dry Ice Pellets sublimate once they've hit the surface (convert directly from a solid blast pellet to a vapour) leaving a clean, dry surface with no residue.
