Dry ice blasting (CO₂ pellet blasting) replaces three categories of industrial cleaning at once: solvent cleaning, abrasive blasting, and manual scraping. The reason it's spreading across industrial accounts in the Northwest isn't the technology — it's the math on cleanup, downtime, and substrate damage.
How it works in 90 seconds
Solid CO₂ pellets (-109°F) are accelerated through a compressed-air nozzle at the substrate. On impact, three things happen simultaneously: kinetic impact dislodges contamination, thermal shock embrittles it, and the CO₂ sublimates (solid to gas) — leaving zero secondary waste. The only thing that needs cleanup is the contaminant itself.
High-fit industrial applications
Manufacturing line maintenance. Mold release, ink, food residue, adhesive overspray, conveyor belts. Cleans around running equipment without shutdown in many cases.
Power generation and electrical. Transformers, switchgear, motor windings, generator stators. Non-conductive, non-abrasive, no residue. Often performed on energized equipment with proper procedure.
Fleet maintenance. Engine bays, undercarriages, drive-train components. Removes grease, road grime, oil without chemicals or steam.
Food and beverage processing. Bakery ovens, dairy lines, bottling equipment, freezers. FDA-recognized as a food-safe cleaning method.
Restoration. Fire, smoke, and mold remediation on structural members, HVAC, and historic buildings.
Aerospace and rail. Composite parts, brake components, rail-car interiors. Non-abrasive on critical substrates.
Where dry ice is not the right tool
- Heavy mill scale and structural steel prep to NACE/SSPC spec — abrasive blasting is faster and produces the required surface profile.
- Removing thick industrial coatings — possible but slow; abrasive wins on cost.
- Dirty outdoor yards with no cleanliness or downtime constraint — the per-hour premium doesn't pay back.

The cost math that surprises people
Dry ice blasting is more expensive per hour than abrasive cleaning — typically 1.5–2.5× the hourly rate. The math flips when you include:
- Secondary waste disposal (zero for dry ice, 5–20× the contamination volume for abrasive)
- Operational downtime (often zero for dry ice, full shutdown for abrasive)
- Substrate replacement or refurbishment (zero for dry ice, episodic for abrasive)
- PPE and containment (minimal vs full for silica)
On clean-environment work in food, electrical, and restoration categories, dry ice almost always wins total job cost.
CO₂ supply and logistics
Dry ice pellets are produced on-demand and shipped from regional plants. Lead time on a typical industrial cleaning project: 24–72 hours from quote to onsite. For ongoing accounts, we maintain CO₂ supply schedules with regional producers.
What a real industrial scope looks like
A proper scope of work specifies: substrate type, contamination type, areas to be cleaned (with photo documentation), production-rate constraints, energization status, containment requirements, and disposal of contamination removed. Vague scopes produce vague pricing.
