Cleanroom Ethanol (EtOH) Solutions

Fast, low-residue disinfection for daily cleanroom control — sterile options available.

Ethanol is one of the most relied-on disinfectants in cleanroom environments because it’s simple, fast, and proven for routine microbial control. In critical areas, 70% ethanol is the standard daily concentration: the water content helps ethanol work better on microbes and keeps surfaces wet long enough to achieve effective kill, while still evaporating quickly and leaving minimal residue. Cleanroom teams use EtOH as the “between-steps” disinfectant—the quick, repeatable wipe that keeps bioburden low during normal production.

In practice, ethanol is used on benches, carts, equipment exteriors, doors, pass-throughs, and other high-touch surfaces where contamination is most likely to transfer from people or airflow. It’s also commonly used to sanitize gloved hands in sterile and compounding areas, and to remove light films, smudges, and fingerprints without introducing heavier detergent residues. Many facilities include ethanol as a final wipe after stronger disinfectants or sporicides, helping remove any remaining film and leaving surfaces clean, dry, and ready for the next operation.

SOSCleanroom has supported contamination-control programs since 1981, and we carry both sterile and non-sterile ethanol solutions to match your cleanroom class and SOP. Sterile EtOH is packaged for clean transfer into aseptic suites and regulated workflows, while non-sterile EtOH supports general controlled areas and support rooms.
