Gamma irradiated wipes are simply exposed to gamma irradiation—there is no standard of efficacy for sterility. Your odds of having a critical cleaning consumable could be 10-to-1 just as easily as it could be 1,000,000-to-1—there’s simply no way to tell.
Additionally, even if it was sterilized properly by the manufacturer, it will not be packaged according to validated sterile standards and could become critical cleaning by the time it reaches your facility. Gamma irradiated products cost significantly less than validated sterile products because far less time, effort and care goes into their production.
The Cornerstones of Validated Sterile Cleaning
Aseptic cleanrooms and facilities may vary greatly, but validated sterile clean wipes and isopropyl alcohol (IPA) should be constants in standard operating procedures (SOPs) for aseptic cleaning protocols. Clean wipes serve wide-ranging critical cleaning control tasks, from managing spills and applying chemicals to maintaining the integrity of work surfaces and equipment.
With extremely low chemical residues, VOCs, and chemical and mineral adulterants—coupled with wide-ranging chemical compatibility—isopropyl alcohol (IPA) is one of the most versatile cleaning agents available. In fact, USP <797> states that 70% IPA should be applied to everything from supplies and shipping containers to hard surfaces and gloved hands.
