Residue is a major concern for manufacturers. Consequences of inadequate residue removal include undesirable appearance (spotting, staining), poor coating adhesion, low yield, and catastrophic product failure.  To successfully remove residue it is useful to understand what that residue is and where it came from.  Also consider: what is it you […]

One Clean Source reader asked a question about the need to run cleanliness testing. “Have you ever written an article that explains why/not ionic contamination testing is required if using no-clean fluxes?” In a global sense, the question is related to: How clean is clean enough? When do you need […]

In a recent LinkedIn post, one of our colleagues, Randy Leighty, comments that “experience is a great teacher, but it can be an obstacle to innovation and continuous improvement.”  We ask: Is experience inherently an obstacle to improvement? Let’s start with a round of applause for inertia! Critical cleaning involves […]

Never use a consumer/automotive cleaning agent for precision cleaning high-value product. True or false Quick! True or false. This is a timed test, and you will be graded. I hate true/false tests; there’s no room for nuance. In critical and precision cleaning, particularly of high-value product, most decisions are situational. […]

High-value product has to be clean to function reliably; but nearly all manufacturing processes inevitably generate soils. You should know about an important new guidance document. While it is designed for medical device manufacturing, it should be of value to anyone concerned with cleaning and contamination control. “Tell me the […]
