What is dry ice blasting?

Dry ice blasting (CO₂ blasting) is a non-abrasive, non-conductive industrial cleaning method that uses solid CO₂ pellets accelerated by compressed air. Pellets sublimate on impact, leaving no secondary waste — only the original contaminant for disposal.

Is dry ice blasting safe on electrical equipment?

Yes. CO₂ is a non-conductive dielectric medium, so dry ice blasting is the preferred method for cleaning de-energized switchgear, motors, transformers, MCCs, generators, and bus ducts per NFPA 70E procedures.

Is dry ice blasting food-safe?

Yes. CO₂ is FDA, USDA, and EPA approved for cleaning food contact surfaces. No chemicals, no water, and no abrasive media are introduced.

Does dry ice blasting damage the substrate?

No. Dry ice is non-abrasive and does not erode steel, aluminum, paint, rubber, wood, or concrete when used with correct nozzle and pressure parameters.

How does dry ice blasting compare to sandblasting and pressure washing?

Unlike sandblasting, dry ice leaves no grit residue and does not erode substrates. Unlike pressure washing, dry ice introduces no water — no dry-out time, no rust, no electrical hazard, no contaminated runoff.

What areas does Dry Ice Blasting Of America serve?

All 48 contiguous United States, with planned outage support available to all 50 states. Standard scheduling within 1–2 weeks; emergency outage support within 24–72 hours. Call (866) 648-0030.

How quickly can DIBA mobilize for a power plant outage?

24–72 hours for emergency HRSG and power generation outages. Same-week mobilization for standard scope across the 48 contiguous states.

What is the typical ROI of switching to dry ice blasting?

Most customers see 40–80% reduction in downtime, 25–60% lower cleaning labor, and elimination of secondary waste disposal. Typical payback is 3–12 months with Year 1 ROI of 150–400%.

Dry Ice Blasting vs Pressure Washing: A Practical Comparison

Pressure washing relies on water. Dry ice blasting eliminates it. That single difference reshapes when each method makes sense.

Pressure washing is fast, familiar, and cheap per square foot — when the target can tolerate water. The problem is that most industrial equipment cannot. Water leaves behind moisture, corrosion, microbial risk, and electrical hazards long after the crew has packed up. Dry ice blasting solves that by replacing water with sublimating CO₂ pellets.

Where pressure washing fails

Around energized or de-energized electrical equipment and controls
Inside dry production environments (bakeries, snack lines, dry mixing)
On insulation that absorbs moisture and harbors bacteria
On corrosion-sensitive substrates and tight-tolerance machinery
On equipment with bearings, seals, or electronics that cannot be re-sealed afterward
Where wastewater capture, treatment, or permitting would be required

Where dry ice blasting wins

Power generation switchgear, MCCs, transformers, and HRSGs
Food production lines that cannot be hosed down between shifts
Mold and fire restoration where moisture worsens damage
Equipment with sensitive electronics nearby
Injection molds and tooling cleaned in-press
Anywhere the cleanup of the cleanup is the real cost

Where pressure washing is still the right call

Open structural steel, parking decks, building exteriors, heavy equipment yards, and any outdoor surface that needs bulk dirt removal and can drain freely is still a pressure-washing job. Dry ice blasting is not trying to replace your pressure washer for those tasks.

Total cost, not hourly rate

Pressure washing looks cheaper by the hour. Dry ice blasting wins on total cost when you factor in teardown, drying time, wastewater handling, corrosion risk, restart delays, and the chance you damage something expensive with water that should not have been wet in the first place.

Bottom line

If water is acceptable, pressure wash it. If water is the problem, dry ice blast it. Call (866) 648-0030 if you are not sure which side of that line your equipment falls on.
