Dry Ice Blasting vs Media Blasting
Complete Comparison Guide
An honest, detailed comparison to help you choose the right cleaning method for your project. We explain when dry ice blasting excels and when media blasting might be the better choice.
Quick Verdict
Choose Dry Ice Blasting When:
- No secondary waste or embedded particles
- Clean in place without disassembly
- Safe for electrical and electronic equipment
- FDA approved for food processing
- No media contamination risk
Consider Media Blasting When:
- Better for surface profiling requirements
- Can achieve specific surface finishes
- Some media more economical for heavy removal
Dry ice blasting excels when you need to clean without leaving any residue or changing surface profile. Traditional media blasting is better when you specifically need surface profiling for coating adhesion.

How Each Method Works
Dry Ice Blasting
Dry ice blasting propels solid CO2 pellets at supersonic speeds. Upon impact, the dry ice sublimates (converts directly to gas), lifting contaminants through thermal shock and kinetic energy without leaving any secondary waste.
Key Benefits
- Non-abrasive - preserves surface integrity
- No secondary waste - only removed contaminants
- 100% eco-friendly - uses recycled CO2
- Safe for electrical equipment
- FDA approved for food processing
Media Blasting
Compressed air or mechanical wheels propel the selected abrasive media at the surface. Different media provide different levels of aggressiveness, surface finish, and cleaning capability based on hardness, shape, and size.
Also known as: Abrasive media blasting, Particle blasting
Pros and Cons
An honest look at the strengths and weaknesses of media blasting.
Media Blasting Advantages
- Wide range of media for different applications
- Can be tailored to surface sensitivity
- Effective surface profiling for coatings
- Some media are recyclable
- Good for achieving specific surface finishes
Media Blasting Disadvantages
- All methods create secondary waste
- Requires containment and cleanup
- Media can embed in substrate
- Dust and particle exposure hazards
- Cannot clean in place for most applications
- Different equipment needed for different media
Best Use Cases
Media Blasting Works Best For
- Surface preparation requiring specific profiles
- Removing coatings when profiling is desired
- Parts cleaning in controlled environments
- Deburring and finishing operations
Media Blasting Not Ideal For
- In-place equipment cleaning
- Electrical components
- Food processing areas
- Areas where media contamination is a concern
Dry Ice Blasting vs Media Blasting FAQ
The key differences are: No secondary waste or embedded particles and Clean in place without disassembly. Additionally, dry ice blasting leaves zero secondary waste because CO2 pellets sublimate on contact. Media Blasting requires significant level cleanup (rated 5/5) and has moderate surface damage potential (rated 3/5).
Dry ice blasting typically costs $6-15 per sq ft per square foot while media blasting costs $3-12 per sq ft. However, dry ice blasting often provides better total value because there is no secondary waste disposal cost, reduced labor for cleanup, and equipment can often be cleaned in place without costly disassembly. For media blasting, you must also factor in significant cleanup and disposal costs.
Media Blasting may be the better choice when: Better for surface profiling requirements; Can achieve specific surface finishes; or Some media more economical for heavy removal. It is particularly effective for Surface preparation requiring specific profiles. However, if surface preservation, zero waste, or electrical safety is a priority, dry ice blasting remains superior.
Media Blasting is not recommended for: In-place equipment cleaning, Electrical components, and Food processing areas. In these cases, dry ice blasting is the safer and more effective choice because it is non-abrasive and leaves no residue that could interfere with subsequent processes.
The primary disadvantages of media blasting include: All methods create secondary waste; Requires containment and cleanup; and Media can embed in substrate. These limitations often make dry ice blasting a better choice for restoration projects, food facilities, and applications where surface integrity matters.
