In this article, we will discuss the best practices for cleaning cleanroom walls, so your facility can operate at optimal levels.
Subheading 1: Understanding the Importance of Walls
walls are a significant component of contamination control. These walls serve as barriers between the external environment and the cleanroom. They must prevent the entry of contaminants and maintain the integrity of the cleanroom environment. Regular cleaning and maintenance of cleanroom walls not only helps to maintain the physical structure of the room but also keeps contaminants under control.
Subheading 2: Preparing for Wall Cleaning

- Turn off HVAC system and close all room doors to prevent dust from entering.
- Unplug all electrical pharma machinery from the walls.
- Cover all pharma machinery with protective plastic sheeting.
- Wet mop the floor of the cleanroom with a disinfectant solution.
- Put on the proper protective clothing, including gloves and goggles.
These preparatory measures help to mitigate the risk of additional contamination to the cleanroom during the cleaning process.
Subheading 3: Cleaning Materials for Walls
When cleaning cleanroom walls, it is crucial to use cleaning materials that do not generate particles. The goal is to remove contaminants from the walls, not introduce them. -specific cleaning materials are the best option, such as lint-free wipes, mops, and buckets. Using standard cleaning materials that generate particles can result in contamination of the cleanroom.
Subheading 4: Techniques for Cleaning Walls

Subheading 5: Proper Cleaning Solution for Walls
The cleaning solution used for cleanroom walls should have a neutral pH to prevent damage to the walls. Acidic or alkaline cleaning solutions can erode or change the properties of the walls, leading to further contamination. A mild detergent solution, such as a mix of hydrogen peroxide and water, is usually sufficient for cleaning cleanroom walls. Avoid using any cleaning agents that produce vapors that could contaminate the cleanroom air.
Conclusion:
Cleaning cleanroom walls is an essential element of maintaining contamination-free environments. Cleaning should occur at regular intervals, using appropriate techniques and materials.
