This process sterilizes the surfaces within a chamber wherein a first portion of the surfaces is at a temperature below 10.degree. C. and a second portion of the surfaces is at a temperature greater than 20.degree. C. The process includes the steps of introducing vapor phase hydrogen peroxide to the chamber, contacting the first portion with the vapor to effect condensation thereon, contacting the second portion with the vapor, applying a source of vacuum to the chamber and continuing to introduce vapor phase hydrogen peroxide into the chamber until the surfaces are sterile while preserving the temperature ranges of the first and second portions.
