What is Better for Removing Contaminants: Dry Ice Blasting or Sandblasting?

Key Takeaways:

Among the most popular industrial cleaning methods available, dry ice blasting and sandblasting are very different in their respective mechanisms for cleaning contaminants from surfaces. Dry ice blasting uses the three-step process of kinetic impact, thermal embrittlement, and rapid gas expansion to separate contaminants from substrates.

Sandblasting, on the other hand, uses pure kinetic impact with a grinding effect to scrape contaminants away. While sandblasting has long been a method for industrial cleaning, it is very messy and time-consuming, whereas dry ice blasting is quick and efficient.

Which Method Provides the Stronger Clean— Dry Ice Blasting or Soda Blasting?

Key Takeaways:

Dry ice blasting is a popular choice because of its ability to clean effectively in a non-abrasive way, produces no secondary waste, can clean equipment in-place, and is suitable for many applications. Soda blasting has also remained a popular option in industrial cleaning, but produces toxic waste, has limited applications, and still requires shutdown and disassembly of equipment for cleaning.

Dry Ice or Soundwaves — Which Cleans Better? 

Quick Answer: Is dry ice blasting better than ultrasonic cleaning?

For most industrial cleaning applications, dry ice blasting is the more versatile and practical choice. Dry ice blasting can clean large machinery in-place without shutdown, disassembly, or moisture while producing zero secondary waste. Ultrasonic cleaning is effective for small, removable parts that can be fully submerged, but it cannot clean live electronics, porous materials, or anything too large to fit inside a tank. If portability, minimal downtime, and a dry, non-conductive process are critical factors, dry ice blasting is the stronger choice.

Buying an inexpensive dry ice blasting machine is tempting, but you will not get the value you would with a high-quality Cold Jet blaster.

Ever since Cold Jet pioneered the modern dry ice blasting machine back in the late 1980s, there has been a multitude of cheaper versions that have captured the attention of contractors, facility managers, and business owners alike. However, just like anything in this world, you get what you pay for. More premium dry ice blasters like those from Cold Jet deliver a superior cleaning experience while budget dry ice blasting systems will often offer a subpar experience.
