Mastering Cleanroom Wiping Techniques for Maximum Efficiency

A cleanroom’s performance heavily relies on the quality of its cleaning process. Proper wiping techniques are crucial to effectively remove contaminants without introducing new ones. Using the correct wiping technique ensures that the environment and process stays in optimal condition. 

 Step-by-Step Guide to Proper Wiping 

• Wipe from cleanest to dirtiest: Always start from the cleanest area to avoid spreading contaminants. This method ensures that no previously cleaned areas are contaminated from more contaminated surfaces.

• Wipe in one direction: Avoid circular or back-and-forth motions. Instead, wipe in a single direction (top to bottom or left to right) with steady pressure. This technique helps contain contaminants in the wiper, reducing the chance of spreading them to other areas.

• Use parallel, overlapping strokes: Ensure that your strokes overlap to cover the entire surface and avoid missing areas. Overlapping prevents any uncleaned spots and ensures uniform cleaning across the surface. 

• Change the wiper cleaning surface frequently: To avoid redepositing contaminants, frequently change the wiper surface during cleaning. 

 Damp vs. Over wet Wiping: 

Wetting levels are critical in ensuring effective cleanroom cleaning. A proper wetting level helps solubilize and lift contaminants effectively, ensuring particles and residues are fully captured in the wiper without being reintroduced to the surface. 

• Damp wiping: This is ideal for solubilizing contaminants and transporting them into the wiper. It helps prevent dry contaminants from dispersing into the environment. Damp wiping also reduces the risk of reintroducing contaminants into the air, as the moisture holds particles in place.

• Over wet wiping: While useful in some cases (such as soaking hardened deposits, applying disinfectants), over wet wiping can spread contaminants. Excess liquid can carry contaminants to other surfaces or leave behind residues, compromising the cleaning process. 

 Conclusion

By mastering proper wiping techniques and using high-performance cleanroom wipers, the integrity of your cleanroom can be maintained, extending the life of your equipment. Following established wiping and cleaning protocols is essential for ensuring a contamination-free environment. Proper technique paired with the right tools can significantly reduce the risk of contamination and improve operational efficiency.
