Dry Ice Blasting for Mold Remediation: A Practical Guide to Surface Cleaning and Limits

Dry Ice Blasting Can Support Mold Remediation — But It Is Not the Whole Process

Dry ice blasting can remove surface contamination from suitable materials without adding liquid water. A proper remediation plan must also correct the moisture source and address contaminated materials, containment and verification.

Potential Advantages

• Dry process
• No spent dry ice media
• Access to irregular surfaces
• Generally non-abrasive cleaning

Important Limits

It does not fix leaks or humidity, does not guarantee hidden mold removal and does not replace professional remediation procedures or clearance testing where required.

AI30 Setup

AI30 uses 3 mm or smaller pellets, a 44 lb (20 kg) hopper and 0.66–1.32 lb/min output. It operates at 87–116 PSI with 71–141 CFM machine air demand.

Containment and Safety

Removed contamination can become airborne or fall to surrounding surfaces. Use appropriate containment, filtration, PPE and cleanup. Dry ice also becomes CO₂ gas, so ventilation is required.
