Cleaning is an essential part in the day-to-day running of any cleanroom areas or high-care lab or facility. Both fixtures and fittings need to be clean. However, choosing the wrong method can unnecessarily prolong the cleaning process or even reduce the lifespan of equipment. With many options available and so much equipment to keep hygienic, it can be hard to know what is right for any given context, and with the growing popularity of single-use (pre-sterilised) consumables, how much is necessary.
Historically, a “simple” wash down combining a lot of meticulous hard work with diluted cleaners has often been deemed sufficient. As long as all areas of a cleanroom could be reached with a clean cloth or brush, that was generally considered good enough. A modern auditor would not necessarily agree. A further downside was the time this takes. Add up the hours taken each day, week, month or year and the considerable cost to the business soon becomes apparent.
Yet there are competing influences at work: the risk of an audit failure makes each clean-down business critical, while the drive to reduce operating costs demands that new techniques that could aid smarter, compliant working, are investigated.
