What is dry ice blasting?
Dry ice blasting is a cleaning process that uses dry ice pellets and compressed air to remove contamination from surfaces. When the dry ice hits the surface, it sublimates, meaning it turns from a solid into gas and leaves no blasting media behind.
This makes it useful for jobs where water, chemicals, or abrasive blasting are not suitable.
What can dry ice blasting remove?
Dry ice blasting can remove many types of surface contamination, including:
- Soot
- Smoke residue
- Grease
- Oil build-up
- Carbon build-up
- Production residue
- Dirt and grime
- Surface contamination from machinery, equipment, and hard surfaces
The result depends on the surface type, contamination level, access, and condition of the material being cleaned.
Is dry ice blasting suitable for fire damage cleaning?
Yes. Dry ice blasting is commonly used for fire damage cleaning because it can remove soot and smoke residue from suitable structural surfaces without adding water or chemical residue.
It can be used on selected walls, ceilings, beams, machinery, and hard surfaces affected by fire or smoke damage.
For fire restoration work, we recommend sending photos first so the affected area can be reviewed before quoting.
Can dry ice blasting clean industrial machinery?
Yes. Dry ice blasting is suitable for many industrial machinery cleaning jobs. It can help remove grease, oil, carbon build-up, production residue, and general contamination from machinery and equipment.
In many cases, machinery can be cleaned in place, depending on access, equipment type, and contamination level. This can help reduce downtime compared with more disruptive cleaning methods.
Is dry ice blasting safe for food processing equipment?
Dry ice blasting can be suitable for selected food processing equipment and production areas because it is dry, chemical-free, and leaves no blasting media behind.
Each food processing job should be assessed based on the equipment type, hygiene requirements, contamination level, and site conditions.
Can dry ice blasting be used on electrical or sensitive equipment?
Dry ice blasting may be suitable for selected electrical and sensitive equipment because the process is dry and non-abrasive.
It can be useful where water or abrasive cleaning methods are not suitable. However, these jobs need careful assessment before work begins. Site conditions, equipment sensitivity, power isolation, access, and safety requirements may need to be reviewed first.
Will dry ice blasting damage my equipment?
Dry ice blasting is non-abrasive compared with methods such as sandblasting. It does not use hard blasting media and does not leave grit or residue behind.
However, suitability depends on the equipment, surface condition, coating, contamination level, and required cleaning outcome. Sensitive or technical jobs should be reviewed before cleaning starts.
Do you use water or chemicals?
No. Dry ice blasting does not use water or chemical cleaners during the blasting process.
This is one of the main reasons it is used for industrial machinery, food processing equipment, electrical equipment, fire damage cleaning, and other jobs where moisture or chemical residue may create problems.
Does dry ice blasting leave any mess behind?
Dry ice blasting does not leave blasting media behind because the dry ice turns into gas on impact.
However, the contamination being removed, such as soot, grease, oil, carbon, or residue, still needs to be managed and cleaned from the work area. The amount of clean-up depends on the job type and contamination level.
How much does dry ice blasting cost?
The cost depends on the job size, contamination level, surface type, access, location, and time required.
Smaller jobs can often be quoted directly when clear photos and job details are provided. Larger, technical, or complex jobs may first receive an estimate, with final pricing confirmed after a site inspection.
To help us quote accurately, please send:
- Photos of the area or equipment
- Type of contamination
- Job location
- Access details
- Approximate size of the area
- Required timeframe
- Any site restrictions or safety requirements
Do you need to inspect the site before quoting?
Not always. Smaller or straightforward jobs can often be quoted from photos and clear details.
A site inspection may be required for larger, complex, technical, or sensitive jobs. This helps confirm access, safety requirements, surface condition, contamination level, equipment sensitivity, and the full project scope before final pricing is confirmed.
How long does a dry ice blasting job take?
The timeframe depends on the size of the area, the type of contamination, surface condition, access, and whether the job involves machinery, fire damage, food-processing equipment, or sensitive equipment.
Small jobs may be completed within a shorter visit, while larger industrial or restoration projects may take longer and require planning around site operations or shutdown periods.
Can dry ice blasting reduce downtime?
Yes, dry ice blasting can help reduce downtime on many industrial and commercial cleaning jobs because it does not require water, chemical soaking, or abrasive media clean-up.
In suitable cases, machinery and equipment may be cleaned in place, which can reduce the need for dismantling and extended shutdowns.
Do you clean vehicle underbodies or restoration projects?
Yes, dry ice blasting can be used for selected vehicle underbody and restoration cleaning jobs.
It can help remove dirt, grease, old build-up, and surface contamination from suitable vehicle areas. These jobs are quoted based on access, vehicle condition, surface type, and the cleaning result required.
What types of clients do you work with?
We work with a range of commercial and industrial clients, including:
- Manufacturing plants
- Food processing facilities
- Restoration companies
- Commercial property managers
- Contractors
- Industrial facilities
- Vehicle restoration clients where required
What areas do you service?
Dry Ice Blasting NZ Ltd is based in Christchurch and focuses on South Island projects. Nationwide projects may also be considered depending on the size, location, and scope of work.
For larger industrial, commercial, or restoration jobs, send the project details and location so the team can confirm availability.
Is dry ice blasting environmentally friendly?
Dry ice blasting is considered a cleaner option than many traditional cleaning methods because it uses no water, no chemicals, and leaves no blasting media behind.
It also helps reduce secondary waste compared with abrasive blasting methods. The removed contamination still needs to be handled correctly depending on the job type.
How do I get a quote?
Send your job details, photos, and location. The more information provided, the more accurate the quote or estimate can be.
For smaller jobs, a direct quote may be possible. For larger, complex, or technical jobs, an initial estimate may be provided first, with final pricing confirmed after a site inspection.
