Practical concepts for cleanroom cleaning

A clean case for a systematic approach

Careful thought must be given to a cleanroom cleaning concept. Besides the various norms, guidelines and standards, a number of practical aspects must also be taken into consideration. This especially applies to the use of mops, wipes, cleaning agents, and disinfectants as well as staff training.

When choosing a cleaning system and tools for cleanroom cleaning, the first thing to consider is the suitability of the products and materials: They should be easy to clean (hygienic design), durable, abrasion-resistant, and, in some cases, autoclavable. Compared to stainless steel equipment, plastic materials are much lighter, making it easier to clean walls and ceilings in particular.

DIFFERENT MOP SYSTEMS
Mop systems provide the basis for the cleaning of walls, ceilings, and floors. These can be wetted and used in conjunction with various systems. Pre-saturation systems (boxes) are a useful aid in small, confined spaces where few mops are needed.

DISPOSABLE MOPS VS. REUSABLE MOP CONCEPTS
The key factor when using reusable mops in the cleanroom is the method and quality of the laundry and preparation process – in other words, how they have been decontaminated and, if necessary, sterilized.

THE RIGHT WIPES WITH THE RIGHT PACKAGING
It is a general necessity to check the compatibility of wipes that are used in the cleanroom.

CLEANING AGENTS AND DISINFECTANTS NEED TO BE CAREFULLY CHOSEN
Every surface should be clean prior to disinfection, which means free of production residues, biofilms, or the residue of previous disinfectants. A wipe material with high cleaning efficiency and possibly also a surfactant should be used for this. However, the cleaning agents must not interact. Only then can the entirely clean surface be disinfected.

TRAINING IS EVERYTHING
When using any kind of cleaning system, it is important to give the cleaning staff clear instructions and practical training to ensure that equipment and cleaning materials are used correctly and potential errors are avoided. Staff training courses should be run by qualified trainers who possess practical experience of working and cleaning in the cleanroom.
