Dry-ice blasting is nonabrasive, non-conductive, nonflammable, and non-toxic. Dry-ice blasting is an efficient [3] [verification needed] cleaning method. Dry ice is made of reclaimed carbon dioxide that is produced from other industrial processes, and is an approved media by the EPA, FDA and USDA. It also reduces or eliminates employee exposure ...
In paint-stripping, ice blasting is used to overcome the cohesive bond of the coating. Depending on the paint or makeup of the bond, some coatings cannot be cleaned. Ice blasting is useful in removing lead paint, as it poses the least danger. Ice blasting has the lowest level of airborne contaminants for blasting technology in removing lead paint.
Another approach is with solid cleaning media (blasting) which comprises the CO 2 dry ice process: For tougher requirements, pellets are used while for more sensitive materials or components CO 2 in form of snow is applied. One drawback is the high energy consumption required to make dry ice.
To begin with, a cleaning agent is applied directly to the surface by spraying, brushing, blasting or wiping. This process removes oil, grease, dirt, loose particles, and any other contaminants that may exist on the surface of the material. Characteristics include: cleans almost all electronic assemblies, electrical components, and almost all ...
Micro-abrasive blasting is dry abrasive blasting process that uses small nozzles (typically 0.25 mm to 1.5 mm diameter) to deliver a fine stream of abrasive accurately to a small part or a small area on a larger part. Generally the area to be blasted is from about 1 mm 2 to only a few cm 2 at most.

Nozzle design is the most significant factor in carbon dioxide snow cleaning performance, affecting the size and velocity of the dry ice particles. [ 4 ] : 277–278 Variations in nozzle design have been developed by W.H. Whitlock, L.L. Layden, Applied Surface Technologies, and Sierra Systems Group.
These include water, sand, crushed glass, dry ice and soda. High-pressure water blasting method uses 30,000 psi (210 MPa) water jet system on a truck equipped with vacuum heads to blast out the markings and suction up the water and debris back to the storage area of the truck. The method can remove markers at speeds of 2 mph (3.2 km/h).
