Proper Cleanroom Wiping Techniques

By Christina Adkison

In cleanrooms and other critical environments, it’s important to understand the role that proper wiping technique plays in reliable and consistent contamination control. When cleaning contamination you cannot see, technique is a sure way to know you’ve covered the surface area in question.

Sometimes operators will take a wipe out of a package and wipe surfaces in a circular or random pattern. This may look like the surface is getting clean but is actually ineffective - the contaminants are simply moved about, but not reliably removed from the surface being wiped. A more disciplined wiping approach reliably removes contaminants from the entire wiped surface. Learn about the key techniques to contamination removal.
