Aerosol sprays release particulates and residues into the environment, which can contaminate
sensitive ICT equipment. Such contamination accelerates corrosion, interferes with airflow, and
increases particulate levels beyond ASHRAE recommended limits.
Proper cleaning should use HEPA-filtered vacuum systems or dry wipes, not aerosols. Even odor
control aerosols are disallowed in critical rooms.
Therefore, aerosol cleaning solutions must never be used.
Reference: ASHRAE TC 9.9 “Contamination Guidelines,” NFPA 75 §8.4.
