A dry ice blasting machine for car detailing makes it possible to remove grease, oils, road residues, technical dirt and contamination from the engine bay, underbody, wheel arches, suspension and mechanical components without using water or traditional abrasives. Dry ice sublimates after impact and leaves no cleaning-medium residue: however, the detached dirt remains and must be collected or vacuumed. For localised and mobile operations, SUBLIMA MINI may be sufficient; for frequent professional activity, SUBLIMA MAX is more suitable, while SUBLIMA TOP is oriented towards extensive, demanding and continuous work.
What dry ice cleaning is in car detailing
Dry ice cleaning uses solid carbon dioxide pellets projected by compressed air. The process combines three actions: cooling of the deposit; kinetic impact; rapid sublimation of CO₂. The cold helps make the contaminant more brittle. The impact of the pellets promotes detachment and the transformation of CO₂ from solid to gas helps separate it from the surface. The process does not use water, sand, grit, detergents, solvents or mineral abrasives.
The definition “residue-free” must be used correctly. Dry ice does not leave water, sludge, spent abrasive or detergent. What remains instead is:
- ✓ Dirt and dust
- ✓ Detached grease
- ✓ Fragments of old protective products
- ✓ Removed contaminants
These materials must be collected through extraction, tarpaulins or controlled cleaning.
Why use dry ice in car detailing
The technology is interesting when the aim is to prevent water and detergents from penetrating connectors, wiring, cavities, joints, mechanical components, areas that are difficult to dry, the underbody and internal parts of the engine bay. The main operational advantages are: dry process; absence of residual abrasive; less need for drying; reduced use of detergents; good access to complex geometries; possibility of localised work; reduction of some disassembly operations; cleaning of assembled components, when conditions allow it.
Dry ice cleaning is not, however, automatically safe on every surface. Before treatment, it is necessary to assess: material; temperature; state of conservation; adhesion of finishes; presence of cracks; exposed wiring; aged seals; brittle plastics; bonded surfaces; protective products that must be preserved.
Main applications in car detailing
Cryogenic restoration and decontamination are applied selectively to different areas of the vehicle:
Engine bay
The engine bay can accumulate dust, grease, oil, road residues, carbonaceous dirt, leaves, deposits, maintenance residues and contamination around pipes and components. Dry ice cleaning makes it possible to work without directly introducing water into the area. It can be used on the engine block, supports, casings, tanks, pipes, brackets, metal surfaces, technical plastics, areas around wiring and hard-to-reach parts.
Before the operation, the vehicle must be made safe. The following must be assessed: engine temperature; battery; electrical circuits; air intakes; open connectors; damaged components; deteriorated seals; any leaks. The absence of water reduces the humidity problem, but does not authorise work without analysing the component.
Underbody, suspension and wheel arches
The underbody may present road dirt, dried mud, oils, grease, bituminous residues, contamination, old waxes, protective products and deposits around pipes and supports. Cleaning may be aimed at aesthetic enhancement, documentation of vehicle condition, restoration, surface inspection, preparation before maintenance, removal of accumulated dirt and cleaning of collector cars.
Before starting work, dirt must be distinguished from materials that must remain. A jet that is too intense can remove or weaken protective waxes, underbody coatings, sealants, anti-corrosion protective products, markings, labels and original finishes. On wheel arches, it makes it possible to reach internal linings, edges, suspension, supports, differential housings, transmissions, casings and areas around brake calipers, adapting the configuration to the differences between plastic, rubber, paint and metal.
Classic cars, collector cars, motorcycles and scooters
Dry ice cleaning is particularly interesting when the aim is to preserve original finishes, markings, zinc plating, small hardware, components, controlled patina, underbody appearance and engine-bay details. The objective must not automatically be to return every surface to a new appearance. In conservation restoration, it is necessary to distinguish between dirt, protective grease, original wax, paint, patina, oxidation and historic material. A preliminary sample is essential. The technology applies with similar advantages to the engine, frame, swingarm and transmission of motorcycles, scooters, bicycles and e-bikes, for which SUBLIMA MINI is specifically indicated by FEVI.
Applications to be assessed with particular caution
Dirt detachment by thermal shock requires strict preventive checks on fragile or degraded substrates:
- Painted bodywork, films, PPF and wrapping: The jet exerts impact, cooling and localised stress. The condition of the clear coat, paint adhesion, cracks or previous repainting must be assessed. On films and wrapping, the jet can lift edges, dull the surface or weaken adhesion, always requiring authorisation from the manufacturer.
- Old seals and electrical components: Hardened, cracked, heat-aged or very thin rubber and elastomeric materials can be damaged by the jet. On electrical and electronic components, the absence of water is an advantage, but connectors, insulation, condensation and electrostatic charges must be assessed, making the circuit safe.
- Vehicle interiors: Dry ice can be assessed on some rigid surfaces, seat rails, pedals and technical components. It must never be applied without tests on leather, fabrics, Alcantara, soft-touch coverings, displays, painted plastics, wood, headliners, foams, bonded materials and decorated surfaces.
Removal capacity of dry ice technology
Dry ice cools and detaches oils, grease, road dirt, hard carbonaceous residues and some glues. Very thick organic residues may require several passes, intermediate collection or preliminary removal of the excess part.
What must not be promised: Dry ice cleaning must not be described as capable of eliminating any contaminant, always removing rust, stripping every surface or always avoiding disassembly. Dry ice does not normally create the abrasive profile typical of traditional blasting. It is therefore not the first technology to choose when deep corrosion must be eliminated, mill scale removed, a surface etched, roughness created or very resistant coatings stripped.
How to choose between SUBLIMA MINI, MAX and TOP models
Sizing the cryogenic unit follows the estimate of work volumes and the configuration of compressed air:
- SUBLIMA MINI (Occasional or localised use): Recommended when the service is introduced gradually, operations are localised, the machine must be transported frequently, productivity is not the first criterion and the available compressor has limited airflow.
- SUBLIMA MAX (Frequent professional use): Recommended when cryogenic detailing becomes a recurring service, complete engine bays and underbodies are treated regularly, greater detachment capacity is required and a perfect balance is desired between portability and output with a professional compressor.
- SUBLIMA TOP (Intensive or structured use): Recommended when the service is carried out continuously on complete vehicles, times must be reduced, demanding deposits are handled and the activity has a high-airflow industrial pneumatic system.
Engineering pneumatic parameters and dry ice logistics
The compressor is fundamental: in addition to maximum pressure, effective continuous airflow, pipe diameter and total absence of condensate or oil in the line matter, as these would cause internal ice formation or dosing instability. Pellet freshness, density and correct storage, in insulated and non-airtight containers, determine output; old or partially sublimated pellets drastically reduce the effectiveness of the process. In addition to dry ice, the service cost must include compressed air, labour, extraction and plant depreciation.

Operational safety and carbon dioxide monitoring
CO₂ is a colourless and odourless gas, heavier than air, which can accumulate in low areas and displace oxygen, especially in closed workshops, basements or inspection pits. NIOSH indicates for CO₂ an 8-hour time-weighted average limit of 5,000 ppm and an IDLH value of 40,000 ppm: forced ventilation and low-level extraction must be rigorously sized.
Direct contact with pellets at −79 °C can cause cold burns, requiring the use of insulating gloves and goggles. The high-pressure jet also generates high noise and projection of dirt fragments, requiring hearing protection and visors. Finally, to eliminate the risk of electrostatic build-up, suitable ESD procedures and stable earthing must be adopted.
Frequent mistakes to avoid in dry ice detailing
Correctly calibrating the set-up prevents damage to sensitive surfaces and optimises operating costs:
- Choosing the machine only according to price or undersizing the compressor: A high-performance machine cannot express its potential with insufficient airflows. Pneumatic consumption often affects the budget more than the cost of the unit itself.
- Underestimating productivity or using entry-level models for intensive work: The SUBLIMA MINI is excellent for localised operations or motorcycles, but is not very productive if used daily to strip and clean complete underbodies.
- Confusing the absence of traditional abrasive with absence of risk: Intense cold, kinetic impact and high pressures can still damage old plastics, heat-aged seals or clear coat that is not perfectly anchored.
- Working too close or not collecting detached dirt: Excessively reducing distances increases point intensity and can weaken adhesives or bonded parts. In addition, the ice sublimates and disappears, but grease and dust remain on the floor and must be vacuumed.
- Using old dry ice or ignoring ventilation in closed spaces: Partially sublimated pellets drastically reduce cleaning output. Working in unventilated environments or above pits without forced extractors exposes operators to the serious risk of carbon dioxide saturation.
FAQ on dry ice car detailing
Which FEVI model is most suitable for starting to offer the service?
SUBLIMA MINI is the most consistent model for introducing the service with a lightweight machine and contained pneumatic requirements. It is suitable for localised operations, engine bays, components, wheels and motorcycles. If the objective is to clean complete underbodies regularly, SUBLIMA MAX may be more productive.
What is the main difference between SUBLIMA MINI and SUBLIMA MAX systems?
SUBLIMA MINI prioritises compactness, transport and low air consumption. SUBLIMA MAX offers greater operating capacity and can work with higher airflows, making it more suitable for frequent professional activity. The choice depends on surface, contaminant, compressor and number of jobs, not only on machine size.
When is it advisable to invest in the top-of-the-range SUBLIMA TOP model?
SUBLIMA TOP is indicated when dry ice cleaning is used continuously, on complete vehicles or demanding contamination. However, it requires a high-airflow pneumatic system and suitable organisation for dry ice, ventilation and residue collection.
Does dry ice leave residues? What does “dry cleaning” mean?
Dry ice sublimates and leaves no water or spent abrasive. However, the removed contaminant remains: grease, dust, road residues and fragments of protective products must be collected. “Residue-free” therefore means no cleaning-medium residue, not total absence of material in the work area.
Can electrical and electronic components and wiring be cleaned safely?
The absence of water is a major advantage, but it does not automatically guarantee compatibility with every component. Protection rating, condition, power supply, connections, electrostatic charges and manufacturer’s instructions must be assessed. Components must be made safe before the operation.
Can dry ice remove rust and mill scale?
No, it can remove dirt and contaminants superimposed on rust, but it must not be chosen as a universal replacement for abrasive blasting. Deep corrosion, mill scale and all treatments requiring the creation of a roughness profile for paint anchoring normally require traditional mechanical abrasive technology.
