Volume XIV, Issue 7 - August 2017


To celebrate the Dog Days of August, we decided to lazily reach way back into our archives and reprint one of our early Clean Source features.

I just wanted to be sure that I was still on the [Clean Source] list. The information is strong and has been valuable in the past; keep up the good work.

Is it a Cleaning Step?

Barbara Kanegsberg, BFK Solutions

[Originally published July, 2005]

Identifying the cleaning steps is not necessarily obvious, especially in multi-step processes. In fact, when we consult with our clients, particularly in troubleshooting projects, one of our first bits of detective work involves working our way through the build process and noting the cleaning steps.  It is important to identify each activity that is actually serving as a cleaning process, because, if such a process is unwittingly removed, surface quality and product quality can suffer.

Sometimes a cleaning step is not termed cleaning.   Perhaps the original process designer thought it was more elegant to avoid the word cleaning.  Perhaps the step is thought of as having a function other than cleaning, but it actually serves as a cleaning step as well.  In a more general sense, identifying the cleaning steps involves understanding the function and value (positive or negative) of a particular step to the overall build process. The following examples of cleaning euphemisms may inspire you to revisit the build process to determine if a step actually constitutes cleaning. You may also find the terms helpful optimizing a process, troubleshooting, and achieving lean manufacturing.
